摘要
为了在产品设计阶段评估液压缸缸筒的可靠性,通过ANSYS/APDL构建了其参数化模型,并根据应力-强度干涉理论搭建了其可靠性模型,假设缸筒的几何参数等设计变量服从正态分布,运用ANSYS的概率设计系统PDS对其进行可靠性评估及灵敏度分析,并运用ANSYS的优化设计工具OPT对缸筒进行轻量化。该项研究可用于指导液压缸缸筒及类似元件的可靠性优化设计。
In order to evaluate the reliability of the hydraulic cylinder in the product design stage,the parametric model is built by ANSYS/APDL,and the reliability model is built according to the stress intensity interference theory,assuming that the geometric parameters and other design variables of the cylinder obey the normal distribution,the reliability evaluation and sensitivity analysis are carried out by using the probability design system PDS of ANSYS,and the ANSYS is used the optimization design tool OPT is used to lighten the cylinder.This study can be used to guide the reliability optimization design of hydraulic cylinder and similar components.
