Chapter 1446 The world¡¯s largest and most advanced vibration test bed

Previous page        Return to Catalog        Next page

    "What are you talking about? China Tengfei already has a 35-ton vibration test bench?"

    As soon as Zhuang Jianye finished speaking, the head of the expert team with gray hair, a pair of square-rimmed glasses, and a civilian military uniform asked with surprise: "Are you sure it's a 35-ton vibration test bench?"

    Not only the head of the expert team, but also other expert team members, Navy leaders and chiefs were all staring at Zhuang Jianye with eager eyes at this moment.

    No way, the 35-ton vibration test stand is of great significance to the navy at this stage, especially for carrier-based aircraft. The 35-ton vibration test stand can be said to be a crucial testing equipment.

    It must be known that carrier-based aircraft suffer greater impacts during takeoff and landing than land-based aircraft. Greater impact brings greater vibration intensity. Because of this, the structural strength and equipment of carrier-based aircraft  The degree of firmness of the installation is much higher than that of land-based aircraft.

    The question is whether this high standard can be adapted to the actual use of carrier-based aircraft when taking off and landing on an aircraft carrier. Especially when the aircraft carrier lands, the huge inertial impact force generated when the speed of nearly two hundred kilometers per hour suddenly drops to 0 can be loaded on the aircraft carrier.  On the fuselage, under such repeated conditions, how to ensure the service life of the carrier-based aircraft of tens of thousands of hours?

    This requires a complete set of vibration test equipment to detect the vibration intensity of each system of the carrier-based aircraft in different environments. Even the vibration of the entire carrier-based aircraft requires vibration test equipment to check. Based on this, each system needs to be tested.  Improve and upgrade the deficiencies of each system.

    This shows the importance of this type of vibration test bench. It can be said that without this type of equipment, it would be difficult to build a qualified carrier-based aircraft. Because of this, developed countries have always been concerned about vibration test benches above 10 tons.  Embargoed.

    In addition to a series of aviation products such as carrier-based aircraft, land-based aircraft, and aerospace engines that require vibration test stands to verify their structural performance, a series of aerospace products also rely on vibration test stands to ensure their reliability.

    Because whether it is a civilian launch vehicle or a military long-range missile, the take-off weight is more than 100 tons. The huge thrust of the rocket engine often causes huge vibrations in various components within the rocket. If a screw is shaken off at this time, a line  If it is broken, the entire rocket or missile may be directly damaged.

    There are countless such errors in the history of space launches. If you want to reduce related errors, you must use a large-tonnage vibration test bench to find design or process flaws through continuous testing, and ultimately reduce the risk of rockets or missiles.  Reliability is improved.

    Because of this, restricting large-tonnage vibration test stands is equivalent to restricting the development of a country's aerospace industry. After all, things with low reliability are not a threat at all.

    "For example, New Delhi's medium-range missiles are almost a second-guessing missile. Not to mention its actual combat capabilities, if it can be fired out safely, it is thanks to the beetle's care.

    There are also Iranian missiles, the same is true, and their reliability is also not high.

    The reason for this is that there is a lack of large-tonnage vibration test benches, reliability data cannot be obtained, and at the same time, its own national strength is limited, and there is no determination to never give up until the goal is achieved. In the end, it can only end up with a pot of rice.

    The country is not as embarrassed as New Delhi and Iran, but the overall level is not high. The current maximum tonnage of the vibration test bench is only 18 tons. As the treasure of a certain aerospace institute, it is used in the development of an improved model of a certain type of long-range missile.  Task.

    With such a high standard for a key unit, you can imagine the situation of other units. If you can have a 10-ton unit, you are considered a wealthy person.

    For example, the Northeast Aviation Industry Group is very confident in its carrier-based aircraft because it imported a 10-ton vibration test stand from abroad in the 1990s.

    For this vibration test bench, the Northeast Aviation Industry Group spent a lot of money, using its foreign exchange quota accumulated over the past five years, and purchased it from the United Kingdom at a high price of US$75 million.

    Converted into gold, this money can buy almost 10 tons of gold ingots.

    Yes, you read it right, the price of a 10-ton vibration test bench is the same gold as the same tonnage.

    The reason why it is so expensive is that there is no other way. At that time, China was relatively backward in this regard and could only produce 10-ton mechanical test benches. Not only did it have poor accuracy, but more importantly, it could only do up and down regular vibration tests, and other directions.  The irregular vibration test cannot be done at all.

    Since domestic products are not as good as foreign ones, others will naturally open their mouths and take one bite.

    But no matter what, Northeast Aviation Industry Group spared no expense to make itself a leader in the domestic aviation industry in vibration testing. It is also on this basis that Northeast Aviation Industry Group is undertaking carrier-based aircraft research.I am extremely confident when doing tasks.

    There is no other way. Looking at other domestic aviation companies, there is no other company except Northeast Aviation Industry Group that can perform ten-ton vibration tests. This is the biggest bonus for carrier-based aircraft that can withstand huge impact forces.  thing.

    Of course, seeing the many benefits of the vibration test bench, Northeast Aviation Industry Group naturally wants to install similar equipment with larger tonnage, so that it can get twice the result with half the effort in the development of carrier-based aircraft. However, developed countries are just like discussing, more than 10  Ton vibration test stands are not sold at all, let alone the same tonnage and the same gold, even if you give it to someone with several times the gold, you will smile and let you roll as far as you want.

    In desperation, Northeast Aviation Industry Group could only return in despair, but they were not discouraged. After all, they are still the only aviation company with a 10-ton vibration test bed.

    The reason why it is obvious is that the vibration test bed of China Tengfei has not been made public. Now it has been approved for use on the aircraft and can be made public. Comparing the results, the Northeast Aviation Industry Group is proud of the 10-ton level test bed that has been used for several years.  The vibration test bench is not even a younger brother in front of China Takeoff.

    That is a 35-ton vibration test stand. It is the largest vibration test stand in the world so far. Only NASA obtained this large-tonnage vibration test stand two years ago. It is used for heavy-duty launch vehicles, advanced aircraft and space station modules.  Section vibration test.

    ¡°I didn¡¯t expect that China Tengfei also has such a large-scale vibration test bench?

    Therefore, compared with the simple surprise of the experts of the China Evaluation Expert Group and the leaders and chiefs of the Navy, Huang Feng and other people from the Northeast Aviation Industry Group were truly shocked.

    It is actually the world's largest and most advanced 35-ton vibration test stand. If this is true, what advantage does Northeast Aviation Industry Group have? It is basically being pinned to the ground by China Tengfei and rubbing it as much as it wants!

    "It's impossibleimpossiblethe 35-ton vibration test bench is strictly embargoed overseas, and you can't buy it no matter how much money you spend. How can you, China Tengfei, have one?"

    The core technical leader of Northeast Aviation Industry Group who had previously questioned Tang Lili¡¯s carrier-based aircraft development cycle finally couldn¡¯t bear it any longer and sternly questioned Zhuang Jianye.

    Zhuang Jianye curled his lips and smiled: "The reason why China Tengfei has been able to develop to this point is to constantly break the so-called 'impossible'. What happened to the embargo? Do you believe that in a few years, China Tengfei will embargo them?"
