摘要：

以某超大型辊锻机的气动干式离合器为研究对象，通过数学建模与数值模拟方法，对离合器动作时间进行分析，建立了离合器动作时间参数以及各阶段时间参数及其影响因素的数学模型，得到了各时间参数与其影响因素间的相互关系，获得了相关参数的关系曲线。结果表明，摩擦结合时间与活塞复位时间在离合器动作时间中的占比很大，二者对动作时间的影响尤其显著，并进一步确定了影响离合器动作时间的主要参数，得到了影响离合器动作时间的一般规律。为超大型辊锻机气动干式离合器的设计优化及其对辊锻机工作性能的提升提供了理论基础与依据。

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.
