Optimal Design of Cylindrical Helical Torsional Spring Including Fatigue Reliability

Abstract:

To get a way of calculating the reliability of fatigue life of torsion spring, the paper discussed the optimal design of fatigue reliability for cylindrical helical torsional spring with Monte-Carlo method, and tried to build a new method to analyze the fatigue reliability of cylindrical helical torsional spring. The new method could test different values of parameters of a spring, and it could calculate the fatigue reliability of the spring in every parameter value with about 100 thousand test points with Monte-Carlo method, which can be set to get a better result, and it gave the comparison and selection to designers finally. The method was run with the software-MATLAB. The paper gave an example at last, and it compared the new methods results with ones of traditional design and discussed the differences.
