| Abstract: | For the research and development of a new type of low-speed engine,it is necessary to carry out crush point installation experiment on the main bearing shell.Through the finite element numerical calculation method,the contact opening and the change between the main bearing cap and the bearing block are extracted from the results,and then the tightening pressure of the hydraulic pretensioner of the crush point is obtained through data processing,so as to accurately calculate the installation crush point of the main bearing shell,saving the experimental cost and improved efficiency. |
