Chapter 37: Many, many weaknesses

　　The sample does not come with instructions.
　　 Only Wang Bu'an can explain clearly.
　　 Of course Wang Bu'an knew what was going on. Therefore, he has already prepared the instructions.
　　 The two sides met and immediately sent a thick manual.
How thick is 　　?
　　 Sixteen open, more than five hundred pages.
　　 Niu Jiro saw the instructions and immediately felt that he was going to faint.
　　 Such a thick book, don’t say it’s to figure it out, eat it thoroughly, even if it’s all read, it takes at least one month! What is this not cheating?
　　 These years, crooks actually pack the same as academicians of the Academy of Sciences.
　　 "Wang Bu'an, is there something simpler?" Niu Erlang's personality is a little bit different, and he is straightforward.
　　 "No. You can watch it yourself." Wang Buyan shook his head and said.
　　 He didn't perfuse each other.
　　 is really not there.
　　The technical principles of Cybertron are too advanced, and a few pages of paper are not clear at all.
　　 Transformers are very serious about science. Taking into account the issue of the acceptability of the people on earth, the manual has been revised repeatedly, and many complicated and obscure words have been deleted. I hope that the people on earth can accept it as much as possible. But for a half-hearted technician like Niu Erlang, it is still a book of heaven!
　　Even, for Lao Ge, the oldest technician, it is also a heavenly book.
　　 "Brother Wang, look..." Niu Qinghai smiled bitterly.
　　 "Actually, it is the wiring problem." Wang Buyan said.
　　 "Wiring?"
　　 "What principle do you care about. Pull the wire directly and use it!"
"Ok!"
　　 Niu Qinghai had to agree.
　　 In fact, doing so is a serious violation of operating procedures.
　　 Even if the basic performance, basic principle, and basic parameters of the battery are not clear, it is directly energized and used. In case of a problem, it is not known where the cause is.
　　 However, what Wang Bu'an needs is not the study of hydrogen storage alloy units.
　　 What he needs is an application!
"I come!"
"it is good!"
　　 Niujiro volunteered.
　　The biggest characteristic of the second-year junior is that the newborn calves are not afraid of tigers. In other words, it is not afraid of death.
Electrical connection.
start the motor.
　　 "嗵嗵嗵!"
　　 "嗵嗵嗵!"
　　 The motor spun frantically, making a piercing sound.
　　 Then, in less than thirty seconds, the sound of the motor gradually disappeared. Immediately, a strong burning smell slowly spread in the air.
　　 The voltage is too high, the current is too large, and the power is too strong, and normal electric vehicle motors cannot afford it.
　　 The final result is to burn it directly and die.
　　 Ordinary electric vehicle motors can withstand up to 80 volts.
　　 However, the lowest voltage provided by hydrogen storage alloys is 220 volts. Another option is 380 volts.
　　 Fortunately, Niu Jiro was also prepared.
　　 They have prepared a bunch of 220 volt industrial motors.
　　 is connected.
start up.
　　 "Buzzing!"
　　 "Buzzing!"
　　 The motor made a strong sound, full of power.
　　 I feel that the battery is not connected at all, but the normal 220 volt AC. From the motor point of view, there is almost no problem.
　　 However, the problem came. This AC motor is relatively large and does not have enough space for installation.
　　 An electric car, the two largest parts are the battery and the motor.
　　 Among them, the battery is the most difficult to manipulate.
　　 tried many times, but there is no suitable place.
　　 either protrudes too much left and right, which seriously affects the riding position. Either the front and rear are not balanced and cannot be installed firmly.
　　 "Unless it is to change the shape..." Ujiro frowned and said.
　　 "Simple!" Wang Buyan's eyes lit up.
　　 hydrogen storage alloy can change its shape.
　　You can have any shape you want. The performance is unchanged. The volume is unchanged.
　　 He picked up a hydrogen storage alloy in his hand.
　　 Robot Elf No. 1 immediately began to transform.
　　 was originally a square hydrogen storage alloy, but gradually became a long cylindrical shape.
　　 Its size is exactly the same as the curved beam of an electric car. In other words, it can be directly overlapped with the curved beam. It even directly replaces curved beams.
　　 The toughness, strength, hardness, and corrosion resistance of hydrogen storage alloys are enough to be the bending beams of electric vehicles.
　　Hundreds of tons of pulling force can withstand, let alone a few hundred catties?
　　 "It's amazing!" Niu Jiro clapped and applauded.
　　 "Mr. Wang, do you become magical?" Lao Ge was also completely stunned.
　　 "No! The hydrogen storage alloy itself can change shape." Wang Buan said lightly, "It's just that you don't understand it for the time being."
　　 "It's amazing. It's amazing. It's amazing." Niu Qinghai said to himself endlessly.
　　With the right shape, the remaining puzzles are much easier.
　　 Everyone studied all night and tried repeatedly.
　　 solved many problems and caused more problems.
　　 First of all, the body material.
　　The previous body material was ordinary steel alloy.
　　 Its strength is average, hardness is average, weight is relatively large, corrosion resistance is average, and it is generally used for low-end electric vehicles.
　　 Now, everyone wants to be high-end. After all, this is the latest technology!
　　 You use hydrogen storage alloy with an electric car that sells for only 800 yuan. Everyone feels it is a waste.
　　So, what is the best body material?
　　 must be carbon fiber!
　　Carbon fiber has many excellent properties. Carbon fiber has high axial strength and modulus, low density, high specific performance, no creep, ultra-high temperature resistance in non-oxidizing environment, good fatigue resistance, specific heat and electrical conductivity between non-metal and metal, thermal expansion coefficient Small and anisotropic, good corrosion resistance, good X-ray permeability. Good electrical and thermal conductivity, good electromagnetic shielding, etc.
　　 A certain German brand bicycle uses carbon fiber for the body. Its domestic price has reached an astonishing 100,000 yuan. Individual models can even reach more than 200,000 yuan.
　　 A bicycle collided with a car, and the one with the big head was not necessarily the bicycle. The car may need to compensate a larger amount.
　　 my country can also mass produce carbon fiber. The output is still very large. The only regret is that there are not many high-end products.
　　 low-end products can also meet the needs. But lifespan will definitely be problematic.
　　After pondering for a while, Wang Bu'an discovered that carbon fiber is also the weakness of my country's industry!
　　 my country's own technical reserves are seriously insufficient.
　　 Currently, the high-end products in the international market have reached the T1200 level.
　　In our country, only those below T700 are available for mass production. Even for those below T700, the output is very scarce.
　　 The most terrible thing is that in the carbon fiber industry, my country has never been able to bypass the feud of Dongying.
　　 And Dongying is very vigilant about Huaxia, and its technology is tightly blocked.
　　 Dongying once had an entrepreneur who exported 3,500 kilograms of carbon fiber to China, but was arrested. Two other middlemen were arrested at the same time.
　　 Currently, only two countries have top carbon fiber manufacturers.
　　 One is the TCA of American Emperor.
　　 One is Toray, Mitsubishi, Toho...
　　 "Weakness..."
　　 "Weakness..."
　　 Wang Bu'an can only sigh softly.
　　 Just a few thousand kilograms of carbon fiber is serious enough to be convicted of treason. One can imagine how terrible the technical blockade is.
　　 Must find a way to grab this market.
　　 "Shockwave, do you have a carbon fiber production machine?" Wang Buan asked quietly.
　　 "You have everything you want. Exchange it with belief value." Sasser was very simple.
　　 "Okay!" Wang Bu nodded solemnly.
　　 His unprecedented desire for faith value.
　　 He wants to exchange for the carbon fiber production line.
　　 He wants to make carbon fiber rotten, and no one wants it for 80 cents a catty.
　　 Still technically blocked?
　　 Hold the old yellow calendar for a lifetime.
　　Carbon fiber cannot be used. In the end, Niu Qinghai decided to use a certain type of domestic alloy steel.
　　Wang Buyan’s hard alloy can’t be processed, and he can’t afford it for the time being.
　　 The body material is solved, and then the problem of rubber.
　　The wheels need rubber.
　　 Good quality rubber, long life.
　　 If it is ordinary rubber, it is estimated that four to five years will end.
　　Niu Qinghai has no special requirements on the life of the wheels, as long as it can survive the three-year warranty period.
　　 There are many types of rubber.
　　There are nitrile rubber, butyl rubber, fluorine rubber, neoprene rubber, ethylene propylene rubber...
　　 Most high-end products also need to be imported.
　　 is another weakness.
　　 Among them, nitrile rubber has become the standard elastomer for oil-resistant rubber products due to its excellent oil resistance, heat resistance and physical and mechanical properties. At present, domestic production is insufficient and the annual import volume is about 40,000 tons.
　　 Fortunately, the total value of this market is not large, that is, only a few billion yuan. UU reading www.uukａnshu.com
After 　　, it was a problem with the brake disc.
　　 An electric vehicle with a hydrogen storage alloy unit is very powerful.
　　 Strong power means that the brakes must be very powerful. Otherwise, it must be unstoppable.
　　 Although the speed has been limited to 40 kilometers per hour. However, driven by strong power, ordinary electric car brake calipers can't stop at all. If you don't cut off the power in time, just take it with you.
　　 Niujiro and others have repeatedly studied and tried repeatedly, but in the end, it is impossible to use ordinary brake calipers.
　　 Brake discs must be used. The best is a ventilated dish commonly used in cars.
　　 Then, here comes the problem.
　　How to modify?
　　 How to reduce it?
　　Also, what brake pads are used?
　　Brake pads are basically made of ceramic materials. However, there are many types of ceramic materials.
　　 low-end ceramic brake pads, performance can not meet the demand.
　　 High-end ceramic brake pads must rely on imports, which are very expensive.
　　 This is another weakness.
　　 I feel a lot of weakness.
　　 It is unimaginable that a small electric car has so many shortcomings.
　　 Silicon carbide ceramics, electronic ceramics, barium titanate ceramics, cobalt oxide ceramics, cordierite ceramics, foam ceramics,-low temperature co-fired ceramics...
　　 Just the name can stun a lot of people. Besides, it is a liberal arts dog like Wang Bu'an.
　　 I feel that Du Niang is useless.
　　 completely incomprehensible!
　　 can only rely on the technology of Cybertron.
　　 High-end ceramic products cannot be used, Niu Qinghai finally reluctantly chose domestic ceramic materials.
　　 Finally, the highlight came.
　　How to modify the motor?
