The purpose of this study is a development of a simple strength design method of bolted joint applicable to the general case. Cylinder-cover bolted joint is selected as an example of the axisymmetric bolted joint. The cylinder-cover bolted joint is modeled using spring-beam elements and analyzed with finite element method. A new spring-beam model of cylinder-cover bolted joint is made taking the slip on the bearing surface of bolt head into consideration. Using this new model the relationship between the applied pressure and the stress in the bolt is analyzed. The axial stress and the bending stress in the bolt are measured by strain gages to verify the results from the analysis of the cylinder-cover bolted joint of various geometry. The obtained results are as follows : (1) A simple and useful method to analyze the stress in the bolt in the cylinder-cover bolted joint is proposed. (2) The analytical results show good agreement with the experimental results.
