【摘要】 阐述了机械可靠性设计理论和蒙特卡罗方法。运用ANSYS软件的PDS模块,将有限元方法和可靠性设计理论相结合,对油缸进行二维参数化建模,并编制APDL命令流,建立可靠性分析文件对油缸进行了可靠性设计。设计结果经过了实践的检验,对类似油缸的轻量化设计具有一定的参考价值。更多还原

【Abstract】 The theory of probabilistic design and Monte Carlo method are discussed.Using ANSYS/PDS module and combination of finite element method and the theory of probabilistic design,building the parametric model of cylinder on two-dimension and its APDL command stream,the cylinder is designed.The design result has reference value to the design of similar cylinders with light weight.This has been proven to be feasible in reality.更多还原
