Suspension bracket dynamic impact test tool

Abstract

The invention relates to a suspension bracket test tool, in particular, a suspension bracket dynamic impact test tool. The suspension bracket dynamic impact test tool includes a suspension bracket mounting base for mounting a suspension bracket, an impact transmission shaft which is installed on and is matched with the suspension bracket, an impact bearing structure and a limiting structure; the impact bearing structure includes two supporting plates which are located at two sides of the suspension bracket and are connected with the impact transmission shaft and a web connecting the two supporting plates together; and the limiting structure is used for limiting the rotation of the impact bearing structure and is located between the suspension bracket mounting base and the impact bearing structure. With the suspension bracket dynamic impact test tool of the invention adopted, individual bodies can be tested at the early stage of product development, and impact failure deformation and mechanical properties of the individual bodies in a vehicle collision process can be obtained.

Description

technical field [0001] The invention relates to a suspension bracket test tool, in particular to a suspension bracket dynamic impact test tool. Background technique [0002] Automobile frontal collision is the type of safety accident with the highest frequency, and a large part of the energy for the development of automobile safety performance is invested in the development of frontal collision safety performance. During a vehicle collision, the fracture and deformation of some main structures will have a great impact on the collision result, such as the fracture of the engine mount. However, the existing technical conditions are difficult to accurately simulate the fracture behavior of casting structures such as engine mounts. The conventional method is to define that the mount does not break at the early stage of design or to define a specific time for the mount to fail based on experience, so that It will greatly reduce the accuracy of vehicle collision simulation.
