| Abstract: | Research and application status of tube hydroforming technology at home and abroad was introduced, various schemes of mode-locking mechanism were designed and FEM models were built, and numerical simulation analysis based on ANSYS software was fulfilled. In order to consider the impact of various parameters such as thickness of operation platform, diameter and number of piston on displacement and stress of mode-locking mechanism, sensitivity analysis was carried out, and variational laws of displacement and stress of mode-locking mechanism were obtained. It prevides theoretical foundation for design of forming equipment, and gains initial design purpose. |
