Problems solved by technology

[0003] For the multi-link suspension of vehicles, if the strength design is insufficient, the connecting rods are prone to deformation
At present, the whole vehicle is used to verify the strength of the multi-link suspension. When the strength impact test is carried out on the whole vehicle, the power system, steering system, suspension system, battery pack and other components of the vehicle will be damaged, resulting in the failure of the multi-link suspension. The cost of strength verification of the frame is relatively high

Abstract

The embodiment of the invention provides a multi-connecting-rod suspension strength test bed, and belongs to the technical field of vehicle testing. The multi-connecting-rod suspension is connected with wheels, and the multi-connecting-rod suspension strength test bed comprises a connecting rod assembly and a pendulum bob assembly. The first end of the connecting rod assembly is fixedly connected to the test bed iron floor, and the second end is hinged to one end of the multi-connecting-rod suspension away from the wheels. The pendulum bob assembly is fixed to the iron floor and comprises a pendulum bob, and the pendulum bob can swing and is used for applying impact force to wheels. Whether the strength of the multi-connecting-rod suspension meets the requirement or not is verified by simulating the impact load borne by the multi-connecting-rod suspension installed on the whole vehicle. The multi-connecting-rod suspension strength test bed can replace a whole vehicle for strength verification, and vehicle cost and related test cost can be saved.

Description

technical field [0001] The present application belongs to the technical field of vehicle testing, and more specifically relates to a multi-link suspension strength test bench. Background technique [0002] During the product development process of vehicle components, matching strength impact tests need to be carried out to ensure that the components will not suffer from cracking, fracture and other strength failures during the design life cycle of the vehicle. [0003] For the multi-link suspension of vehicles, if the strength design is insufficient, the connecting rods are prone to deformation. At present, the whole vehicle is used to verify the strength of the multi-link suspension. When the strength impact test is carried out on the whole vehicle, the power system, steering system, suspension system, battery pack and other components of the vehicle will be damaged, resulting in multi-link suspension. The strength verification cost of the frame is relatively high. Conte...
