Application of Simulation Technology on Reliability Analysis for Aircraft Landing Gear System
摘要
Abstract
Dynamic load of landing gear is havier, which leads to complicated operation environment of system and more faults. So research on reliability of aircraft landing gear system becomes more and more exigent and important. Based on the simulation analysis model, the paper presents reliability analysis method for the typical failure mode of the landing gear. The method adopts automatic simulation solution strategy by using the 3D aided modeling software CATIA, the finite element analysis software NASTRAN, multibody dynamics analysis software LMS Virtual Lab and hydraulic pressure control software AMESim. The simulation analysis data is obtained by applying data sharing and fusion mechanism under the different software platforms. Then, combined with high precision, high efficient method of reliability analysis, realize the reliability analysis for the typical failure mode gear simulation. The example of a landing gear drop reliability analysis shows that the method, which based on established simulation model by the collaborative simulation technology of multi-software-platform and the analysis of the failure mechanism and failure modes of mechanism systems, is of the feasibility and practicability for the complex landing gear mechanism systems reliability analysis.关键词
