Vehicle rcar and front and rear end low-speed impact test device and test method based on the device

Abstract

The invention discloses an RCAR (Research Council for Automobile Repairs) and front and rear end low-speed impact test device, and the device comprises an overall support, a pendulum bob installation frame, a pendulum bob, an impact apparatus, a pendulum bob lifting mechanism, a pendulum bob releasing mechanism, a pendulum bob speed measuring mechanism, a pendulum bob braking mechanism, and a main control unit. The main control unit can carry out the automatic linked adjustment of all devices needed by a test according to the type of the test, can automatically adjust the height of the pendulum bob, the pendulum bob speed measuring mechanism and the pendulum bob braking mechanism from the ground, can automatically lift the pendulum bob to a needed height and automatically releases the pendulum bob. The device can achieve a plurality of standard impact testes, does not need to manually adjust the position of each mechanism, and improves the testing efficiency and precision.

Description

technical field [0001] The invention relates to the field of vehicle performance test equipment, in particular to an automobile RCAR and front and rear end low-speed collision test device and a test method based on the device. Background technique [0002] With the improvement of living standards, people's requirements for the safety performance of vehicles are also getting higher and higher. In life, low-speed front-end collisions and rear-end collisions often occur in cities. After the vehicle collides at low speed, the bumper, anti-collision beam and lamps and other related parts will be damaged, which will involve the vehicle maintenance and parts replacement after the accident, resulting in maintenance costs. Under today's regulations, the cost of such repairs is often covered by the insurance company. Therefore, both consumers and insurance companies need to carry out a certain risk assessment on the car's performance in low-speed collisions such as damage resistance...

Problems solved by technology

Due to the complex structure and large overall size of the crash test device, it is difficult to debug the components in the equipment, and the test requires high precision. Therefore, in the prior art, there is no crash test device that can guarantee test efficiency and test accuracy. At the same time, it can be applied to the above three types of standard tests
