Background
In the research and development process of automobiles, the durability of the suspension helical spring is an important detection index, and whether the durability test device can simulate the actual working condition of the helical spring has great influence on the detection result of the durability. For most independent suspensions, different suspension coil springs correspond to different mounting dimensional parameters. In actual operation, the spiral spring is not only subjected to axial tension and pressure but also subjected to bending moment. For example, in a multi-link suspension, the force of the ground acting on the tire is transmitted to the coil spring through the lower control arm, and when the lower control arm rotates, the coil spring is subjected to a bending moment.
At present, most of test devices for testing the durability of the spiral spring adopt a mode of directly connecting a spring mounting seat and an actuator to drive the spiral spring to do stretching and compressing motion along the axial direction. The coil spring is only subjected to axial acting force, the actual working condition of the suspension coil spring in the running process of a vehicle cannot be simulated, and the test result cannot reflect whether the spring has a stress concentration point in the lift process.
