Chapter 267 Two Structures
"Let me explain to you the two power structures that popped up in my mind. If there is anything you don't understand, please interrupt me at any time. Then we are going to divide into several groups and conduct experiments separately." Surrounded by everyone, Lin Wenfang has no stage fright at all, even though machinery and power are not his specialty.However, since he studied with Qiu Ming in Tianchi Mountain, although he has not worked hard in this field, no matter whether it is Qiu Ming or the people who made Tianyao later, they are all top-notch technical talents. He has a very high starting point in both theory and practice, and with the help of Huo Yu, he has crammed a little more during this period, which is more than enough to deal with these people.

The two proposals proposed by Lin Wenfang are very novel.Due to the limitations of small stepping devices on volume and weight, basically connecting rods and metal wires are used to dominate the entire power system. As for the output, small motors are used.Although there is still potential for improvement in the technology of small motors, it is not something that can be accomplished overnight. Chiyi Technology's original main business was drones, and it has a first-class partner in the field of small motors. Don't worry about products in this area. It is Moya's first-class level.The key is the transmission.Whether it is a linear motion or a connecting rod, the biggest problem is the same, that is, it can guarantee a stable and powerful output in one direction, but it is difficult to take into account the other directions.However, a power dog cannot only run in a straight line, nor can it always rely on the speed difference between the left and right sides to turn.If no adjustments are made, the exercise ability of the power dog will be very limited. However, these two most basic structures are not so easy to adjust.

Lin Wenfang never considered the connecting rod transmission method at the beginning.Not only because the link-type transmission itself consumes a lot of power, but also because this method uses a large number of fixed-shaped parts, which itself reduces the flexibility of the entire mechanism a lot.The drive-by-wire drive is much more flexible, and its own weight is very light.There is enough weight difference between the two solutions of wire control and connecting rod for Lin Wenfang to design the mechanism he needs.

The first solution he came up with was very simple, which was to install an adjustable clamp on both sides of each power line. By adjusting the position and direction of the clamp, the power line could move within a certain range, such as the original When the power line perpendicular to the movement direction moves to a parallel position, the power dog can obtain power that can be output laterally to a certain extent.Generally, it seems that there is no way to increase the horizontal output power to be the same as the vertical direction, and it will always lose a lot, but at least it is better than nothing.With the optimization of the structure, it should be possible to allow the lateral output power to reach [-]% to [-]% of the total power.

After this plan came out, everyone was scratching their heads.It is indeed easy to understand, but there are too many wire clips that need to be installed. There are dozens of main power wires on a power dog, that is, hundreds of wire clips. Although the densely packed wire clips are not difficult to install, the number Putting it there will greatly reduce the overall reliability.The more parts, the less reliable, everyone knows this.

Another scheme that caught everyone's eyes, also uses the dynamic power line layout, but the way of activity is very different.In most positions, the power line is a single strand, but in the places where the limbs and the back move most frequently, a power line layout in which one power line is divided into three branches is adopted.The clamps are fixed, but separate from where the joint is mounted.A movable shield-shaped device is installed on the limbs and the main axis of the back, and three grooves are opened on it, so that the three power lines are respectively stuck in the grooves. By adjusting this movable shield, the power line can be changed. The direction of the force is applied, so as to achieve the purpose of adapting the direction of the force output.Compared with the first solution, this method has many advantages, especially the force applied in several directions can be adjusted at the same time, so that the overall power output can be biased to the extreme in an instant, and actions such as high-speed continuous sharp turns can be made, purely speaking in a short time The burst of sportiness, as long as the background driver can keep up, is even stronger than "Shoutian".

But this solution is really challenging. In terms of processing accuracy requirements, the processing accuracy requirements of this solution are extremely extreme in almost every item, at least reaching the level of several major The precision alignment of the device.Those shield-shaped parts have higher requirements, whether it is material, shape design, surface treatment, etc., all have to meet high standards.Especially the material.This metal shield will generate high heat due to the constant friction of metal wires back and forth on the surface.Not only does this part require extremely high precision and strength, but it cannot be solid, and a sheet structure must be milled out on the back to dissipate heat... This is almost an impossible task for Chiyi Technology's current processing technology.

After discussion, in order to convince other companies in one fell swoop at the exhibition, everyone decided to adopt the second solution.If this difficulty can be overcome, the average technical level of the entire company can be raised by one level, which will be of great benefit to future development.In addition, partly because Rostock and Jorgen questioned Ke Yonghua carefully.Since Ke Yonghua has vowed to guarantee that it is no problem for him to process the shield-shaped parts, the other technical difficulties are not very high. Background driver preparation only.Purely from the perspective of dynamic testing, this background driver doesn’t even need to be too complex and precise, as long as it can perform actions such as walking, running, jumping, collision, turning, rolling, and buffering according to the requirements, it is fine. Wingtech thinks that this aspect can also be done better than the requirements of the 9903 Research Institute.Chiyi Technology has a program department, but these people usually work in the office as network management and data services.Jorgen actually temporarily invited some programmers who had worked with him before to take over the company's daily computer system work, freeing these old employees of the company to tackle this project together.

Lin Wenfang was faintly excited.The two power structures he proposed this time are completely different from the multi-point engagement escapement power system that Xiao Tian and Yu Zhuo used to find inspiration from clocks and watches and gradually develop.The power systems of Xiaotian and Yuzhuo are very delicate and meticulous, and are currently the strongest and most advanced in all aspects, but in Moya, this kind of power system is absolutely impossible.Lin Wenfang also has no intention of copying the power system of "Xiaotian" here. I believe that the Moya people have long understood that "Xiaotian" is not the target of their copycats, but that kind of power system will collapse all their suppliers. , the yield rate will be very low.For Moya, that was by no means an economic option.

However, the power system proposed by Lin Wenfang is not entirely aimed at Moya's trap or an expedient measure, but has more ideas in it.Three power lines are not the ultimate goal of this scheme. If possible, this system can incorporate a greater number of power lines, and definitely the more power lines, the better the performance.In Lin Wenfang's idea, the ultimate goal of this scheme is to install a shuttle-shaped power line base around the main axis of the power line, separate the power lines one by one, and install not Simple cable clips, but adjustable cable loops.Through the harness ring, the power is distributed to different power lines to achieve different power output directions.Such a solution can avoid the mechanical movement of the current shield-shaped parts, reduce heat generation, improve reliability, and achieve more detailed and rich power output.This kind of thinking simulates the constriction of muscle lines, but to achieve this, at least the current processing level of Chiyi Technology is not enough.The material and processing precision of the wire harness ring are extremely demanding. I am afraid that it is not easy for Tianyao's technical experts to process it in batches. At most, they can do it manually one by one. There is no need for it.

The plan proposed by Lin Wenfang went through several simulation calculations by Huo Yu, and roughly calculated the best plan, and formed the layout of the power line into a drawing.However, Lin Wenfang couldn't come up with the best solution all at once, so he could only repeatedly try various solutions with the "colleagues" of Chiyi Technology, and gradually came up with the "best solution".

After working in the workshop for almost 12 days, they roughly finished the power dog, but it is still an engineering version. All the lines are exposed, that is, a hard layer is added outside the power lines. The cover is made of translucent resin material, and the other parts are not even the simplest shell.This time I really ran out of time. It is a simple shell, but this shell must also conform to the characteristics of the power dog in motion, and must not have side effects. It's going to be trial and error.But they actually only have one day, and this day will be used for dynamic tests and reports that meet the requirements of the 9903 research institute, and then the group of people must rush to Sidney immediately to participate in the exhibition organized by the research institute meeting.

Ke Yonghua, who holds a C-level safety assessment certificate, is naturally not eligible to participate in this exhibition. When the dynamic test is finished, he and the programmer finally talked about the program adjustment plan, then left and went home to sleep.Everyone in Chiyi Technology was in a state of excitement, they all understood what a powerful thing they sent for public testing.It may seem miserable, but the power dogs they made are even beyond their own imagination in terms of performance.The acceleration, top speed, steering speed, continuous direction change ability, reaction speed and other data of the whole power dog are very satisfactory.Indeed, compared with real police dogs, this thing is absolutely impossible to be flexible enough, but Jorgen inquired about the data obtained by other companies. If not all companies are pretending to be low-key and deliberately concealing the truth, then they have absolutely Big advantages... jaw-dropping advantages.
