摘　　要：为研究自动振打除灰装置活塞在工作状态下的可靠密封,需要选择合适的密封圈.运用CAE软件在自动振打除灰装置活塞与活塞杆密封处分别建立了双Y密封结构和X型圈密封结构的非线性有限元模型,得出了在两种不同的密封圈结构下密封沟槽中的接触应力,Von-Mises应力与工作流体压力之间的关系,对比分析两种计算结果确定了自动振打除灰装置活塞与活塞杆处合适的密封结构.To explore the reliable sealing performances of the piston of rapping device under working condition,we should choose appropriate seal-ring.The CAE software was employed to build nonlinear finite element model of Double-Y and X-ring sealing structure.Under sealing groove of the piston of rapping device respectively,the relationship between contact stress and pressure of sealed fluid and the connection between.Von-Mises stress and pressure of sealed fluid in the sealing groove under two different kinds of leakproof structure are approached.Comparison of the two Calculation results is helpfull to determine the proper sealing structure between the piston and rod of rapping device.
