Abstract

In here, a robust optimization mathematical model of the cylindrical helical compression spring is presented. To minimize the error and maximal variations of spring stiffness coefficient related with structure parameters and its tolerances is chosen as its objective function, and the acceptable region is formed by some constraints. The theory is applied to the structure design of the breaking spring of spring actuator, the breaking characteristics are all satisfied at the optimum structure parameters, and the optimization results are discussed.
