Notes:
In this paper, the variation rules of strength, load, reliability and failure rate of mechanicalcomponents are studied with time, and a state equation model for dynamic reliability of mechanicalcomponents is established under random load. Meanwhile, reliability index is obtained by usingSecond moment method and perturbation method. Based on the reliability design theory andsensitivity analysis method, torsion-bar is taken as an example, and the dynamic reliability sensitivityof torsion-bar is extensively discussed and a computing method is presented for dynamic reliabilitysensitivity design. The variation rules of dynamic reliability sensitivity are obtained and the effects ofdesign parameters on reliability of torsion-bar are studied. As a result, the proposed method providestheoretical basis for reliability design of torsion bar
