doi:10.3969/j.issn.1000-1093.2017.01.026

Abstract

Abstract: Bolt joint is widely used in industry because of its reliability and effectiveness. The joint stiffness plays a very important role in bolt joint structure. A finite method of bolt joint structures under the optimal preload is proposed. The joint stiffness is analyzed for different structural parameters in consideration of the nonlinear factors,such as of force, contact property and friction. The effects of bolt pretightening force, thickness and external diameter of joint member, and nut parameters on joint stiffness are studied. The dimensionless stiffness function expression is derived through the experimental verification of contact surface compressive stress distribution and the assumption of joint stiffness continuity, and the model dimensionless stiffness data is fit. The formula for calculating bolt joint stiffness is developed based on the results of finite element analysis (FEA). The effectiveness and accuracy of joint stiffness calculation formula is verified by comparing FEA results with those from previous studies. Key
