Reliability Sensitivity Analysis of Sliding Bearing Based on Virtual Simulation Technology
As a non-linear finite element analysis software ANSYS/LS-DYNA is used to carry out virtual reliability test in transmission mechanism of reciprocating compressor and response surface method is used to analyze reliability and sensitivity of sliding bearing according to testing data. This paper uses ANSYS to preprocess testing models of virtual prototype and put out the K file; designs sample points of random variables based on central composite method and modifies the K files to carry out random sampling of prototype and uses LS-DYNA970 to solve the submitted K files repeatedly; plots relationship curves of output responses and time history and gets a group of sample points of structure response with post-processing results of LS-PREPOST. Lastly this paper uses response surface method to build limit state equation and analyze reliability and sensitivity of sliding bearing, and provides theoretical basis for design of bearing.
