Abstract�� The Monte Carlo importance sampling method together with response surface, which was used to calculate the mechanisms reliability, was studied. Based on the method, a reliability analysis software for aircraft structural systems was developed, and a case of a elevator control mechanisms was presented to illustrate the method. The analysis results show that this method can enhance the mechanisms reliability analysis efficiency.
