| 摘 要： | 考虑随机不确定性因素的影响,对某型号O形密封圈进行可靠性分析。通过ANSYS参数化语言APDL建立O形密封圈参数化模型,根据应力-强度干涉模型及密封圈的工作特点建立其可靠性模型。假设密封圈的几何参数、载荷及屈曲强度为服从正态分布的随机变量,运用ANSYS的概率设计系统PDS对密封圈进行可靠性计算。利用VB6. 0将ANSYS的APDL代码进行了封装,编写了O形密封圈的可靠性分析软件。该项研究可为液压元件的可靠性计算与专用软件开发提供借鉴意义。

| Abstract: | Considering the influence of random uncertainty,the reliability analysis of a type of O-ring is carried out. The parametric model of O-ring is established by APDL,and the reliability model is established according to the stress strength interference model and the working characteristics of the seal ring. Assuming that the geometric parameters,load and buckling strength of the seal ring are random variables subject to normal distribution,the reliability of the seal ring is calculated by using the probability design system PDS of ANSYS. The APDL code of ANSYS is encapsulated by VB6. 0,and the reliability analysis software of O-ring is compiled. This research can provide reference for reliability calculation of hydraulic components and development of special software. |
