Abstract：

For the pneumatic dry friction brake of a super-large roll forging machine, the relationship between its action time and influencing factors was analyzed, and the mathematical model was established. Then, the relationship curves between the action time and its influencing factors were obtained by the numerical simulation method. The results show that the friction braking time accounts for a large proportion in the action time of brake. The main factors affecting the action time of brake are determined, including intake and exhaust throttling areas and pre-compression amount. The general rule affecting the action time of brake is obtained. Furthermore, the action coordination of clutch and brake is analyzed, and a reasonable coordination scheme is proposed, providing theoretical basis and foundation for the design optimization on the action coordination control of pneumatic dry friction brake and clutch brake for super-large roll forging machines.
