隔膜室盖联接螺栓预紧力的有限元分析

以隔膜泵液力端隔膜腔与隔膜室盖的联接螺栓为研究对象,通过预紧力单元法模拟螺栓预紧力的加载方法,采用有限元软件ANSYS分析预紧力单独作用与预紧力及外载荷同时作用的情况,并进行隔膜室螺栓的接触分析,得出分析隔膜泵螺栓联接能力、预紧效果及失效原因的理论依据。分析结论对料浆输送主要设备隔膜泵联接螺栓的设计制造、安装调试与维护检修具有参考意义。

Finite Element Analysis for Preload of the Join Bolt on Diaphragm Chamber Lid

This paper adopts the preload element method with the ANSYS software to simulate the preloading of bolt for researching the bolt joining the body and lid of diaphragm chamber in the condition of only preload acting and both preload and external load acting.The theory basis,from analyzing the contact condition of the joint bolt,is given to analyze the joint strength,the pre-tightening effect and the reason of failure.The conclusion from the analysis could be taken as reference for the manufacturing,installing and maintaining of joint bolts used in the diaphragm pump which is the main equipment for the transfer of slurry material.
