摘要
考虑随机不确定性因素的影响,对50 MN三梁四柱式锻造液压机工作缸缸体进行可靠性分析。通过ANSYS/APDL参数化设计语言,建立缸体三维参数化模型;根据应力-强度干涉原理,建立缸体可靠性模型;将缸体的几何参数、载荷及屈服强度等参数设为服从一定分布规律的随机变量,运用ANSYS/PDS模块,采用Monte-Carlo模拟技术,对其进行可靠性仿真,给出了缸体的可靠度数值;通过灵敏度分析,探讨了各不确定性变量对缸体可靠度的影响规律。
Considering the influence of random uncertain factors,the reliability analysis for the working cylinder body of the 50MN three-beam and four-post forging hydraulic press is carried out. Using parametric design language ANSYS （APDL）,the three-dimensional parametric model of cylinder body is established. According to the stress-strength interference principle,the reliability model of cylinder is constructed. Setting the geometry size,load and material strength of the working cylinder body as random variables obeying a certain distribution,using the ANSYS/PDS module and Monte-Carlo simulation technology,the paper analyzes the reliability of the cylinder body. Through the sensitivity analysis,the influence of the uncertainty variables on the cylinder body reliability is discussed. This study can provide a theoretical basis for the design of the working cylinder body of the forging hydraulic press,and it has important significance for the reliability research of the cylinder block.
