基于CAE的Y形高压往复密封材料性能对比

Comparison of Y-sheped High-pressure Reciprocating Seal Material Performance Based on CAE

聚氨酯和丁腈橡胶是高压往复密封件的常用材料,但材质的选择一直缺乏成熟的理论和试验依据.本文以Y形密封为对象,基于CAE技术对高压背景下两种材质的密封特性进行了仿真分析,探讨不同密封系统的介质压力、密封接触面摩擦系数以及往复密封滑动速度等参数变化对密封结构最大接触压力和最大剪切应力的影响规律,研究两种材质在高压往复运动下的破坏规律,准确呈现不同工况下两种材质性能的优劣,为特定工况密封件的选择提供数据参考.

Polyurethane and nitrile rubber are commonly used materials for high-pressure reciprocating seals,but the selection of materials has always lacked mature theoretical and experimental foundations.This paper focuses on Y-shaped seals and conducts simulation analysis of the sealing characteristics of the two materials under high pressure by using CAE technology.It explores the influence of changes in parameters such as medium pressure,friction coefficient of sealing contact surface,and sliding speed of reciprocating seal on the maximum contact pressure and maximum shear stress of the sealing structure.The study investigates the failure patterns of the two materials under high-pressure reciprocating motion,accurately presenting the performance advantages and disadvantages of the two materials under different operating conditions.This research provides data reference for the selection of seals under specific working conditions.
