摘要
分析了聚乙烯排料罐的失效原因,并采用ANSYS软件对可能的失效原因进行了验证。针对原设计中存在的问题,提出了两种改进措施:(1)对支座垫板设置圆角;(2)在对支座垫板设置圆角的同时增加支座数量。对改进后的设备进行了有限元模拟。改进后排料罐原失效部位的应力状况得到了很大改善,在实际应用中取得了很好的效果。
Analyzed the potential failure reasons of a polyethylene discharging tank, verified the analysis result by ANSYS software. To solve the problems existing in the original structure, put forward two improvement measures, one was to manufacture the bearing plate with rounded corner, the other was to increase the number of bearings based on the former measure. Conducted finite element simulation for the improved tank, the results showed that the stress condition of failure position had been greatly improved. The improved tank achieved good results in practical application.
