Problems solved by technology

When carrying out the fatigue durability test of the swing arm, it is necessary to apply loads to the swing arm ball pin 16 from the three directions of X, Y, and Z. However, the existing test benches generally only carry out uniaxial loading fatigue tests along one direction. , failed to simulate the multi-axis working conditions, resulting in the fatigue failure mode of the bench test inconsistent with the actual working conditions

Abstract

The invention discloses a swing arm part durability test stand. The swing arm part durability test stand comprises actuators, test sample mounting frames and a multi-component-force loading mechanism, wherein the actuators are connected with the multi-component-force loading mechanism for simultaneously applying acting forces in multiple directions to a test sample through the multi-component-force loading mechanism. According to the swing arm part durability test stand, a multi-component-force loading system is formed by use of the actuators and the multi-component-force loading mechanism, the loading process of a swing arm part in a vehicle test can be truly represented, and the purpose of consistency between the test stand and a failure mode in the vehicle test is realized.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a durability test bench for swing arm parts. Background technique [0002] In automobile chassis suspension, especially MacPherson suspension and double wishbone suspension, the swing arm plays a pivotal role, and its fatigue durability is related to driving safety. During the use of the vehicle, the position of the swing arm ball pin is affected by multi-directional loads. [0003] figure 1 Shown is a schematic diagram of an existing double-wishbone suspension of a car. In the double-wishbone suspension 10, two bushings 12 on the right side of the lower swing arm 11 are fixed on the subframe, and the two bushes 12 are coaxially arranged so that the lower swing arm 11 can rotate around the axis. The lower wishbone 14 of the shock absorber 13 and the inner ring of the bushing 15 in the middle of the lower swing arm 11 are fixedly connected by bolts. There is rubber between the inner...
