Test car used for testing rodless airplane tractor

Abstract

The invention relates to the technical field of aviation ground facilities, and in particular relates to a test car used for testing a rodless airplane tractor. The test car is characterized in that the test car is provided with a load-bearing platform, wherein the load-bearing platform is provided with a cab, a power control system, a hydraulic control system and an electrical control system; the upper end of the load-bearing platform is provided with a balance weight assembly; the lower end of the load-bearing platform is provided with a support wheel group; and the front end of the load-bearing platform is provided with a nose wheel device. Because of adopting the structure, design parameters of the rodless airplane tractor, such as torsion, over turn, traction force and the like, can be detected; the weight and the inertia, the front undercarriage weight and other parameters of various airplanes can be simulated; the traction capability, the elevation capability and the safe protection performance of the rodless tractor can be detected; the performance parameters of the various airplanes are verified on one set of detection equipment; the potential defects existing in the design and production process of the rodless airplane tractor can be reduced; the product testing capability of tractor manufacturers can be enhanced; and various potential safety hazards can be eliminated for airports and airlines.

Description

technical field [0001] The invention relates to the technical field of aviation ground facilities, in particular to a test vehicle for simulating some parameters of an aircraft and testing various design parameters of a rodless aircraft tractor. Background technique [0002] As we all know, there are many aircraft tractor manufacturers at home and abroad, and the models of aircraft tractors produced by them are too numerous to enumerate. The towbar tractor tows the aircraft through the tow bar and does not directly contact the nose landing gear of the aircraft, so the inspection requirements are relatively loose. However, the rodless tractor is in direct contact with the nose landing gear of the aircraft, so it needs higher reliability and aircraft adaptability. This puts forward strict requirements on the design parameters of the rodless tractor. [0003] At present, there are more and more types of rodless aircraft tractors used in civil aviation airports, the tonnage i...

AI Technical Summary

Problems solved by technology

[0003] At present, there are more and more types of rodless aircraft tractors used in civil aviation airports, the tonnage is also increasing, and its functions are becoming more and more complex, but its various tests are not in place, and can only be described by the original manufacturer Its functions and parameter performance cannot issue convincing file reports and data reports, which has many unpredictable security risks

If these potential safety hazards are not eliminated in time, it will not only cause economic losses to tractor manufacturers, but also to airports and airlines, and even endanger the precious lives of passengers. Generally speaking, the consequences are very serious.

The best supporting facility for the test of the rodless aircraft tractor is the aircraft, but the price of using the aircraft test is very expensive, there are many types of aircraft, and the risks in the test process are also great, and the airlines will not provide the aircraft As a test; according to international industry standards, it is forbidden to use the aircraft as the test object in the test process of the rodless aircraft tractor. The above factors make it difficult for the rodless aircraft tractor manufacturer to carry out detailed technical verification of the vehicle

Therefore, the supporting test vehicle is the main bottleneck in the development of the rodless aircraft tractor
