The material of spring is 50CrVA wire, service life (Cycle times N) is 106.
Design Variables.This problem requires weight design; the spring weight (W) should become the objective function.The formula of W is: (1) Among them: —material density, density of steel is —number of death circles, , determined From the formula, we can see the key is to select the appropriate parameters of the spring (and), in order to keep the spring lightest.
