Research on Simulation Calculation of Kinematic Accuracy Reliability for Folding and Deploying Mechanism Considering Gaps of Kinematic Pair

For evaluation problems of kinematic accuracy reliability for folding and deploying mechanism under the condition of small sample,  the continuous contact effective coupling model considering gaps of kinematic pair is built by using "effective length model" theory; Based on the proposed kinematics model of folding and deploying mechanism, simulation calculation method of mechanism kinematic accuracy reliability is proposed by the Monte-Carlo method, kinematic accuracy reliability for folding and deploying mechanism of certain type missile wing is calculated, the attained reliability is 4.87% lower than that under condition of not considering gaps of kinematic pair. The calculation result shows that the reliability obtained by the method proposed in this paper is more closely to the engineering practice
