Abstract:
A contact bolt model is proposed as a new modeling technique to investigate the complex structure with bolted joints for modal analysis and compared with the coupled bolt model,and the test results are given.Among these models,the coupled bolt model provides the best accurate responses compared with the experimental results.The contact bolt model shows the best effectiveness and usefulness in view of operational time.The bolt models proposed in this study are adopted for a dynamic characteristic analysis of...
