Commercial vehicle mudguard support assembly test stand and endurance test method

Abstract

The invention discloses a commercial vehicle fender bracket assembly test bench and a durability test method, which belong to the technical field of performance testing of automobile products, and include a linear actuator, a connecting fixture, a fender bracket and a fender assembly; Wherein, the connecting fixture includes a fixture bottom plate and a bracket connecting vertical plate, and the clamp bottom plate is used for connecting the fixture bottom plate with the top disc of the linear actuator; the bracket connecting vertical plate is connected with one end of the fender bracket; The other end of the fender bracket is fixedly connected with the fender assembly; the structure is simple and compact, has high versatility, saves time and high efficiency, is easy to process, and has high work efficiency. The durability test method described in the present invention aims at strengthening the road load spectrum signal in the test field, and can truly reproduce the vibration state and the vibration state in the vertical direction of the fender bracket assembly in the test room under the actual vehicle working condition by means of simulation iteration. In order to realize the durability performance assessment and test certification of the fender bracket assembly.

Description

technical field [0001] The invention belongs to the technical field of performance testing of automobile products, and in particular relates to a commercial vehicle fender bracket assembly test bench and a durability test method. Background technique [0002] With the continuous advancement of science and technology and the continuous improvement of living standards, people have higher and higher requirements for the performance of automobile products, and the high reliability of the complete vehicle and its parts is an important symbol of modern automobiles. [0003] As a car protective structure, fenders can reduce the damage to the vehicle surface caused by gravel flying out with the wheels on the road, and can reduce the pollution of mud and water splashing on the vehicle surface in rainy days. For commercial vehicles, the fender is mainly connected to the frame longitudinal beam through the bracket structure, so it is particularly important to evaluate the durability of...

Problems solved by technology

[0005] So far, the domestic automobile industry’s evaluation method for the durability test of the fender bracket assembly is mainly to monitor during the vehicle road test and proving ground test, which is time-consuming and laborious, and the repeatability is poor, which affects the product development process; bench test The method can overcome the defects of the real vehicle road test method to a large extent, but there is no test bench for testing the durability of the commercial vehicle fender bracket assembly
