Abstract

In order to improve the design reliability of retracting actuator, the reliability analysis is taken by NESSUS software based on the stress - strength interference theory. The design reliability value was obtained. The sensitivity and importance analysis on random variables which affect the design reliability were done. The result shows that the design reliability value is 0.99999999986, and the relative error between the test value is 1.3E-10, which is acceptable in engineering. The parameters that have relatively greater effect on the reliability and ordered by influence degree are diameter of shear pin, active area of output pressure, gunpowder impetus and density of detonator output charge. The consistency of these parameters should be guaranteed in material selection and product processing.
