Reliability Simulation of Fretting Wear Based on Neural Network Response Surface in Space Structure Latches
For the repeated docking of structure latches which lead to the fault mechanism of the fretting wear, it is established the model for the fretting wear fault mechanism of latches. Then the main parameters which have influence on the fretting wear are determined through the analysis of structure kinematics simulation. On this basis, for the nolinear and implicit limit state function, comprehensively considering of the random factors such as a variety of materials, damping and rigidity coefficient and so on, it is put out the method of multidisciplinary neural network and the response surface model to simulate the limit state function based on fretting wear of structure latches, and carried out the simulative analysis for wear reliability. Finally it is obtained the relationship between the locking docking times and the fretting wear reliability, and it realizes the comprehensive designing analysis for wear life and reliability of the space mechanism onorbit, and explores the engineering research for the design analysis technology for reliability and life of the complex mechanism of spaceflight.
