A dynamic model of wing unfolding mechanism was established by Adams.Based on the momentum exchange theory, a joint defining method was set up to take into account clearance of joints.Then, the kinematic accuracy of wing unfolding mechanism was analyzed.Considering random factors in geometry and load conditions, kinematic accuracy reliability and sensitivity analysis of the unfolding mechanism were carried out by the fourth moment method.Reliability of the unfolding mechanism and sensitivity of basic random parameters were obtained as a result.The sensitivity results show that improvement of combustion-gas-actuated cylinder's reliability has great effect on reliability enhancement of unfolding mechanism.Meanwhile, improvement of machining and assembling techniques may increase mechanism's reliability.
