Interstellar Mecha Life

Chapter 58

So Qi Yue chose to combine topics and knowledge points to explain.

After a few minutes, Angel, Lulu, and Claude also arrived one after another, and they did not interrupt Qi Yue, but sat quietly at the back of the small classroom.They saw that there were about a dozen people gathered here, quietly listening to Qi Yue's explanation, they were surprised and gave each other a look.

"The model of the mecha and the matching of parts." Qi Yue noticed that there were many questions of this type in the primary assessment, and Huihui had also mentioned to her the headache of this type of question before.

Matching is a typical topic in the primary exam, and there are many of them.The explanation given in the exam syllabus is to examine the basic knowledge, requiring the examinee to have a relatively comprehensive understanding of the overall situation of the current mech industry.Maybe it's because of a better memory, or maybe it's because he is interested in all kinds of mecha mechanical materials, and after knowing it deliberately, Qi Yue has never found them to be difficult.

However, memory is not the only way.

A dozen or so people in the classroom watched Qi Yue remain silent for a while, then suddenly asked a question: "What do you think must be considered in the selection and design of mechas?"

Sitting in silence, no response.

A few people were slightly surprised, and looked at Qi Yue with a little more curiosity.They are all old students who have participated in many assessments, and for the assessment, they have also attended many remedial classes.Every time this kind of topic is mentioned, the teacher who lectures simply says: just memorize it.

They won't be so distressed if they can bear it.

The mainstream mecha standard, there are more than [-] kinds of large and small in terms of appearance alone, and each size needs to use different materials for different purposes, maintain different mecha weights, equip different accessories, and various combinations Counting down, there are hundreds of types of mechs.

Each rack is as large as the type and size of the plate, as small as a small fingernail-sized part, hardware such as the joint drive shaft of the mech, and software such as various drives or computing systems of the mecha.Each has standards, and each must be memorized.

A simple calculation requires the number of models to be memorized to reach [-].This is simply fatal.

Seeing no one answered, Qi Yue didn't wait too long, and continued, "I think it's about balance."

"A 13-meter-high land combat mech, with an upper body weight of 4.7 tons and a waist shaft diameter of 1.12 meters, is only equipped with an atmospheric flight system. What type of leg armor should I use?" Qi Yue asked a question.

In fact, this is a multiple-choice question, but she didn't talk about the options one by one, explaining the model of mecha they match. "If you have back information, you must know that the leg armor should be made of 20A high-strength alloy, and the standard leg armor is 4.7 meters long. If you don't remember it, you must make a choice. I tend to analyze it from the perspective of balance .First of all, the characteristics of the land combat mech is to ensure that the mech can adapt to various land conditions. It can cross, climb, step, and run. The legs of the mech are long and the weight is moderate, so that it can keep the center of gravity low and flexible features."

After Qi Yue habitually analyzed the characteristics of the land combat mecha, he suddenly realized that he was lecturing to others, rather than teaching the concept in a comprehensive manner. How to use this feature to solve the problem? In fact, just like the analysis just now, if you understand the characteristics of the land combat mecha, even if you don’t remember the model, you can choose the option with a reasonable weight and length.

"If you don't understand, there are actually ways to do it. Personally, I prefer to use the simulation computing system equipped in the assessment. This system is very powerful. The more you know, the more problems you can solve."

As she spoke, she operated the simulator on the podium, causing an analog computing system to appear in the holographic projection area in front of everyone.

"In this system, we need to simplify the mecha first, input data, and make a preliminary balance simulation." Qi Yue said according to the topic, input several data into it, "First draw a circle to represent the head , a 13-meter mecha, the size of the head does not exceed 1 meter, and the weight is less than 0.3 tons. Then the hands... the upper body...all of these are 4.7 tons according to the title."

Several circles with weight and size labels appeared in front of Qi Yue.

"Now let's try to bring the error option in... draw two ellipses to act as legs. Then set the gravity system... start the simulation. See, the mecha has no problem standing, walking, wobbling, climbing... Notice that when When the lighter material is used for climbing, one leg is raised, and the top-heavy mech is easy to topple over. This is obviously an unqualified choice.”

In the previous life, when theoretical mechanics had not yet developed to this level, the kinematics of the rigid system had always been the most troublesome.But after 3000 years, even the auxiliary tools included in the assessment can do this kind of calculation.

This system is actually not intuitive, like many mecha simulation systems on the Internet, it will not display a realistic mech.So few people think of using it for balance testing.Qi Yue first discovered it when calculating multi-body motion.

Later, she suddenly realized that the mecha itself can also use this system to analyze the force and balance. Although it can only be estimated roughly, it is simple and fast.It is very suitable for rough calculations in the initial modeling.

Most importantly, this is the calculation system that comes with the assessment and can be used by candidates freely.

The students sitting here are experienced in many battles, so they naturally know the existence of this system.But they never thought of using it for balance analysis, let alone such a rote problem can be solved in this way.

Surprised, everyone started experimenting with the computing system and whispering to each other.When everyone found that almost 70.00% of the matching type problems can be solved by the method Qi Yue said, they all admired and smiled uncontrollably on their faces.

After that, Qi Yue talked about a few more knowledge points, and shared some simulators he used in the early days of learning mechs with everyone for practice.

During the explanation process, people often ask questions.For example, at this time, a clear boy asked: "The same shoulder bearing, Type 47C and Type 47D can meet the balance requirements, and the role in joint rotation is generally the same. But why is it usually used in interstellar mechs? Type 47C?"

Qi Yue raised her head, feeling that there seemed to be more people.

But she didn't care, nodded and said: "We can take a look at the internal structure of the interstellar mecha."

Qi Yue unfolded the three-dimensional model and enlarged the shoulder: "Actually, many part models are not only related to this part itself, but to other adjacent or even non-adjacent systems. If you can't find the answer from itself, you might as well Expand your field of vision a bit.

"The choice of this shoulder bearing is an example. The flight system of the star mecha is quite special, using a vacuum flight system. Because of its volume requirements and structural arrangements, it needs space to place the snake of the fuel processing system near the shoulder. shaped pipe."

The model is zoomed in again, and the bends of the pipes and the proximity of the bearings are clearly shown.If the 47D type bearings are used, the serpentine tube will be too close to the shoulder joint system, almost touching.This is obviously an unreasonable arrangement.

Lulu whispered at this time: "I don't know if it's an illusion, but I always feel that Qi Yue has memorized a lot of things in such a short time, and I usually can't remember anything even if I memorize it for a long time."

Angel nodded when he heard it, and began to analyze: "Simply reciting memory is definitely not as impressive as practicing it yourself, and it is intuitive. Although it seems to be easier to recite, you can know a lot of things in a short time. But it comes and goes quickly. Quickly. In the end, it will become memorization in order to cope with exams and questions. I will go to it later. Moreover, it is painful and difficult to memorize. But Qi Yue has rich experience in assembly, and his understanding of many things is not limited to memorization in books. For her, it is not a rigid standard, but an object that she touches every day. Because she understands and is familiar with it, it is naturally convincing.”

He thought for a while, and then continued: "And I think her rich and comprehensive knowledge is also a very important reason. Many standards about mechs are now few people understand why they are stipulated in this way, and what is the principle behind them. Because even mechas Teachers in the department or technicians with many years of experience can only focus on their own specialties. But many regulations are synthesized. I am afraid that if it is not someone like Qi Yue who has covered a wide range of subjects, it will be difficult to understand the reasons behind many standards.”

I don't know if Qi Yue's lectures are easier to understand, or because everyone is too eager to learn, this class lasted until six o'clock in the evening, and everyone was hungry.The small classroom was full of people at some point, and some people even stood in the open space behind, quietly listening to Qi Yue's explanation.

They are all students who passed by during the lecture and were attracted, or were called by friends.

When Qi Yue noticed this, she couldn't help becoming nervous.After talking about the last knowledge point, he finally stopped and discussed with Huihui, who was sitting in the front row, how to deal with the current situation.

At this time, there was a murmur of discussion in the classroom.

"Isn't it? Is the tall man standing behind the judge's driver? The one who won No.1 in the inter-school competition this time?"

"It seems to be." Someone confirmed, "I also know the one next to him. He is the founder of the Supernova website, Bronski... Ah, and the one standing in the innermost one is Su Yu, the senior of the communication. I heard that Su Yu A member of the family. He should be a graduate student this year, right? He came to listen to this?"

"What's going on? Why did they all come over..."

At this time, a person next to him interjected: "I watched them come down from the sixth floor, and I heard that there are people from the Wuyun Mecha Team there."

"Wu Yun's people? They are not Wu Yun's, right? If Su Yu remembers correctly, he should be a member of the pinnacle's reserve team? Bolanski has never heard of it..."

"It's not now, doesn't it mean it can't be in the future?" The person who interjected disdainfully said, "I heard that Wu Yun is wooing them. Especially the pilot of the judge, who defeated Wu Yun twice, Ke told him Very caring."

When Huihui explained the situation to the people in the classroom and said that the explanation was over, the students in the small classroom, regardless of whether they knew each other or when they came here, couldn't help but stood up and applauded, and gave Qi Yue applause of gratitude and admiration.

Everyone left one by one, and soon the small classroom seemed empty again.Huihui hopes to invite Qi Yue to dinner and expresses her gratitude to her.Qi Yue originally wanted to decline.Although she had been talking for so long, her mouth was a little dry, but after all, she was talking about something she liked, and the whole process did not feel strenuous to her, on the contrary, it could be said to be enjoyable.

But seeing Huihui's eyes full of anticipation, Qi Yue couldn't refuse.

At this moment a person stopped her.

"Student Qi Yue, can I have a chat with you?"

Qi Yue turned her head and saw that it was a boy she didn't know.After taking a rough look, she had to admit that this boy was quite good-looking, and he was a little extravagant from head to toe, giving him the feeling of a son of aristocratic family.Those golden pupils shone with a seductive brilliance.

But she has no intention of agreeing to the invitation.She has the heart to refuse Huihui's invitation, so how can she agree to a stranger?Just when I was about to decline politely, I heard the boy speak again, with a playful and mysterious voice: "I didn't receive a reply to the email I sent you today, but we met anyway. Remember your promise? ? Qi Yue."

Qi Yue suddenly knew who the person in front of him was.
