| Abstract: |
| In allusion to issues such as excessive deformation and loosening of the pressure plate bolt connection system in the long-term service process of a marine wet friction clutch under complex working conditions, the work aims to study the deformation of the pressure plate in the pretightening process of the pressure plate bolt connection system, and optimize structure of the bolt connection system of the clutch pressure plate. The finite element simulation software was used to establish a simulation model of the pressure plate bolt connection system, and the simulation analysis method was verified by experiments, the effects of the tightening torque, bolt specifications, pressure plate flange thickness, and pressure plate thickness on the load and deformation of the connection system were analyzed. Through the deformation test, it was found that the error between the test and simulation data was less than 6.7%, which verified the reliability of the simulation method. The pressure plate deformation was the largest in the pressure plate bolt connection system, followed by the bolt deformation, and the base deformation was the smallest. The pressure plate deformation and stress change were negatively correlated with the bolt specifications and positively correlated with the tightening torque. Increasing the thickness of the pressure plate flange and pressure plate could significantly reduce the pressure plate deformation and stress. Under the condition of considering the entire connection system installation space, it is suggested to add a f 285 mm×1.5 mm flange at the end face of the pressure plate and increase the pressure plate thickness to 24 mm. |
