Abstract

The invention provides a method for designing a spiral spring of an automotive suspension. The method comprises the following steps of acquiring a designing parameter of a suspension system; determining an initial basic parameter of the spiral spring according to the designing parameter of the suspension system; determining the structural shape of the spring according to requirements on space of the suspension; determining a variable parameter corresponding to the spring according to the selected structural shape of the spring; calculating a spring wire diameter according to the determined variable parameter and a selected spring material; calculating a spring structure parameter and a spring performance parameter according to the spring wire diameter, the initial basic parameter and the selected spring material; and checking and judging a spring designing scheme according to the spring structure parameter, the spring performance parameter and the selected spring material. According to the method for designing the spiral spring of the automotive suspension, the spring wire diameter can be calculated directly; when springs with different structural shapes are designed, the variable parameters on calculation of the wire diameters are correspondingly changed, and the corresponding spring structure parameters and corresponding spring performance parameters can be calculated accurately.

Description

technical field [0001] The invention relates to the technical field of automobile suspension, in particular to a method for designing an automobile suspension coil spring. Background technique [0002] In the suspension system that uses coil springs as elastic components, coil springs are one of the very important parts, which not only affect the fatigue life of the vehicle, but also have a decisive impact on the ride comfort of the vehicle. It can be seen from this , Spring design is an important part of automobile design. [0003] like figure 1 As shown, at present, the design method of automotive suspension coil springs is generally to first select a spring wire diameter (material diameter), then calculate other parameters of the spring, correct the value of the wire diameter according to the calculation situation, and recalculate the relevant parameters , so repeatedly. The variable parameters for calculating the wire diameter of springs with different structural shap...
