摘　　要：采用有限元技术,应用ANSYS程序软件分析螺栓联接问题,建立计算模型,施加边界条件并进行求解,得到螺栓联接结构的应力分布情况。该种计算方法能够充分考虑螺栓联接结构的应力集中和接触特性的影响,可用于解决大型水轮发电机组部件联接等问题。A computational model was established using the finite element technigue and the ANSYS program software,and the stress distribution in a bolt-joint structure was obtained by applying the boundary conditions for solution of the bolt-joint structure problem.This way of computation can take into full consideration the influences of stress concentration and contact properties of a bolt-joint structure,and can be used to solve the joint problems of large turbine power generator components.
