自走式谷物联合收割机后桥的有限元分析

摘要

利用ABAQUS有限元分析软件对自走式谷物联合收割机的后桥进行了静力分析,获得了后桥的应力分布结果,2个套管底面靠近内侧处应力最大,最大应力为130.5 MPa.通过结构优化,将后桥设计为空心,其强度仍然满足要求.%The stress distribution of the rear axle of the self-propelled combine harvester was obtained through the static analysis using the finite element analysis software ABAQUS. The results show that the maximum stress was lain on the inner side of two pipes bottom and the maximum stress reached 130.5 Mpa. Furthermore, the optimal design indicated that the the rear axle strength was sufficient even if the hollow rear axle was applied.
