摘要

建立了带接触单元的非线性有限元模型，用于评价螺栓-螺母-垫圈-压片连接系统的接触状态。应用适当的材料规律，从夹紧力的角度研究了接头构件的非线性行为。根据有限元计算结果，对接触螺纹间的载荷分布和系统的实际预紧力图进行了评估。为了在中等强度螺栓上产生所需的夹紧力，建议使用热处理垫圈代替低强度垫圈。

Non-Linear Finite Element Analysis of the Contact, Strain and Stress States of a Bolt-Nut-Washer-Compressed Sheet Joint System

A non-linear finite element model with contact elements was developed to evaluate the contact state of a bolt-nut-washer-compressed sheet joint system. Applying the proper material law the non-linear behaviour of the members of the joint was studied in terms of the clamping force. Based on the FE results the load distribution among the threads in contact and the real preload diagram of the system were evaluated. To produce the required clamping force at medium strength bolts it is advisable to use heat-treated washers instead of lower strength ones.
