Novel vehicle door hinge and stopper integrated test bench rack

Abstract

Disclosed is a novel vehicle door hinge and stopper integrated test bench rack. The novel vehicle door hinge and stopper integrated test bench rack is composed of a rigid bench rack, a stopper moment detection module, a displacement / force detection module, a simulation rigid engine cover, a simulation rigid side door and an impact speed detection module. The rigid bench rack and the stopper moment detection module are combined to detect the opening / closing moment of a vehicle door stopper; the rigid bench rack, the displacement / force detection module and the simulation rigid engine cover are combined so as to be able to detect horizontal rigidity and over-opening rigidity of an engine cover hinge; the rigid bench rack, the displacement / force detection module and the simulation rigid side door are combined so as to be able to detect the sagging rigidity of a side door hinge and the over-opening rigidity of the vehicle door stopper; and the rigid bench rack, the simulation rigid side door and the impact speed detection module are combined so as to be able to detect the impact-resisting strength of the vehicle door stopper. The advantages are as follows: the versatility is high, the simulation degree is high, the labor intensity is reduced, the test efficiency is improved, and the novel vehicle door hinge and stopper integrated test bench rack is suitable for a vehicle side door hinge, a side door stopper and an engine cover hinge.

[0003] Mechanical performance testing of vehicle components usually includes tests for strength, stiffness, fatigue, and functionality. For these tests, a testing system is usually used that includes a test bench for mounting the part to be tested and a control cabinet with various control components However, ordinary test benches are often aimed at one or several mechanical performance tests of a specific product, and their versatility is not high. Due to their strong specificity and low modularity, it is not conducive to the upgrade and expansion of the test system. Therefore, , how to improve the versatility of the test bench for the upgrade and expansion of the test system has become an urgent problem to be solved

[0004] Door sagging stiffness test: In order to test the automobile door hinge assembly after opening a certain angle, apply a downward load along the Z direction in the vehicle body coordinate system at a specified distance from the hinge axis, and measure the simulated rigidity of the door at the place where the load is applied. Elastic deformation and plastic deformation, and obtain the relative curve of deformation and load; the previous test method is to manually load the weight of fixed weight to generate load on the rigid car door, and use the displacement measuring device to detect the deformation after the load is generated; the above test method The disadvantage is that the load is not loaded at a uniform speed, which affects the accuracy of the collected data; manual loading is labor-intensive and the work efficiency is low

[0005] Door stopper opening and closing torque test: In order to verify the limit effect of the stopper on the door during the opening and closing process and the hand feeling of opening and closing the door; the previous test method is to make a special test fixture, and drive the test fixture to switch the limiter through a torque wrench , at the same time read the door opening and closing torque at the gear position; the disadvantage of the above test method is that it can only read the maximum torque generated at each gear position, and cannot measure the real-time torque of each angle when opening and closing the door, and cannot output the torque / angle curve picture
