摘　　要：为解决复杂截面应力、变形问题的求解,以柱体扭转问题的应力函数及多连域转化为单连域的方法为基础,应用有限元-边界元法,提出了"孔洞拟填充"的方法,并利用有限元分析软件ANSYS Workbench以偏心轮为例模拟求解扭转问题.结果证明该方法可以适用于任何截面的杆件.By the finite element/boundary element method, on the base of torsion problems of the cylinder stress function and converting multiple-connected regions into simple-connected region method, this paper proposes a ＂hole and dummy filling＂ method to solve the problem of stress and strain of complicated section. Using eccentric wheel as an example, the problem of torsion is ana- lyzed by ANSYS Workbench finite dement software. The study proves that the method is applica- ble to bars with arbitrary cross-section.
