Abstract：

For the pneumatic dry clutch of a super-large roll forging machine, the clutch action time was analyzed by mathematical modeling and numerical simulation methods, and the mathematical models of clutch action time parameters and time parameters of various stages as well as their influencing factors were established. Then, the mutual relationship between the each time parameter and their influencing factors were obtained, and the mutual relationship curves of relevant parameters were acquired. The results show that the friction engagement time and piston reset time account for a large proportion in the clutch action time, and both of them have a significant impact on the action time. The main parameters affecting the clutch action time are further determined, and the general rule affecting the clutch action time is obtained, which provides theoretical basis and foundation for the design and optimization of pneumatic dry clutch of super-large roll forging machine and the improvement of working performance on the roll forging machine.
