运用APDL的柴油机曲轴可靠性分析
Reliability analysis of the diesel engine crankshaft based on APDL
摘要
Abstract
The overall three-dimensional parametric model of the crankshaft has been completed based on the ANSYS Parametric Design Language(APDL) from the software of ANSYS and by combining the structure analysis capability with the statistical analysis capability of its PDS module, the reliability analysis of Monte Carlo finite element method will be achieved according to the finite element analysis technology and the reliability basic principles. The 4110 diesel engine crankshaft was taken as an example,the parametric design will be introduced into the finite element structure analysis to implement the rapid adjustment of the structure parameter ,produce the anatomic model automatically and complete the process of the structural analysis and reliability analysis. The process that the reliability analysis of the crankshaft has been realized will be described in detail. According to the results of probability analysis, the sensitivity relation between the design variable and the object variable will be obtained and at the same time the maximum stress probability distribution function of these dangerous pans and the main affective factor for object variable will be given ,which will offer the useful data for the structure reliability optimization design.关键词
