摘要:
针对机械振打器活塞杆易于断裂的情况,利用有限元方法对气化炉机械振打器活塞杆的断裂进行了研究,得出了活塞杆Vonmises应力云图以及几何突变处不同的倒角半径对应的最大应力值.结果表明:活塞杆的最大应力发生在截面的几何突变处,且最大应力值随着倒角半径的增加而减小.其结果有助于对危险部位失效进行可行性预测,此预测对活塞杆的结构设计具有重要意义
Abstract:
Based on the actual working conditions,the performance of piston rod about rapping device of gasifier were analyzed by using finite element method,obtained the Vonmises stress contour of piston rod and the maximum stress value of the different fillet radius at the varying crosssection. The results show that the maximum stress of piston rod occurred in the varing crosssection,and the maximum stress increases as the fillet radius decreases.The results was helpful to conduct a feasibility prediction for the risk crosssection, which is important for the the structural design of the piston rod.
