Problems solved by technology
[0007] However, limited by the special structure of the shock absorber fork, it is not a regular-shaped force-bearing structural member, so it is difficult to quickly and accurately measure its working load. Therefore, it is difficult to provide accurate load input for the design of automobile suspension

The invention discloses a passenger car suspension system shock absorber fork working load test method. The test method comprises the steps of applying tensile load to a shock absorber fork for multiple times, collecting strain data of specific positions on two fork arms of the shock absorber fork and applied load data in real time, processing the strain data and the applied load data in a linear fitting and averaging mode, then obtaining load and strain calibration coefficients, and finally, in the road test, multiplying the collected strain of the shock absorber fork by the load and strain calibration coefficients to obtain the working load of the shock absorber fork. According to the invention, the working load of the shock absorber fork of the passenger car suspension system can be rapidly and accurately tested at low cost, and reliable basic data are provided for the development of a front suspension system of the passenger car.
Description
technical field [0001] The invention belongs to the technical field of working load testing of passenger vehicle suspension system parts, and particularly relates to a working load testing method of a shock absorber fork of a passenger vehicle suspension system. Background technique [0002] Suspension system is an important part of the car, which has a great influence on the ride comfort and handling stability of the car. [0003] Double wishbone independent suspension is widely used in the design of automobile suspension for its advantages of high lateral stiffness, excellent anti-roll performance and good grip performance. [0004] The double-wishbone independent suspension consists of two upper and lower V-shaped or A-shaped control arms of unequal length and a strut-type hydraulic shock absorber. Usually, the upper control arm is shorter than the lower control arm. One end of the upper control arm is connected to the strut shock absorber, and the other end is connected...
