Research on Time-variant Reliability and Time-varying Global Reliability Sensitivity of Aircraft Landing Gear Mechanism
摘要
Abstract
For a certain type of aircraft landing gear mechanism,considering the characteristics of random and time-varying of the load and resistance,the time-varying global reliability sensitivity analysis theory is used to study the effect and interaction mechanism of random factors on the landing gear mechanism.The output response of each input variable sample value is obtained with the joint simulation of MATLAB and ADAMS.Based on the neural network and adaptive Kriging model,the agent model of limit state function is established.Sampling method is used to realize the calculation of time-variant reliability and time-varying global reliability sensitivity of the landing gear mechanism.关键词
