现代船用摩擦离合器设计时,不仅要进行静态设计,以满足传递最大扭矩的要求,而且应该进行动态设计,控制热负荷所引起的温升和应力在许用范围内。本文以干式锥形高弹性摩擦离合器为例,根据热弹性理论和有限差分原理,对船用摩擦离合器接合过程的动态温度场和应力场计算提出了一种方法,为离合器动态设计提供条件。一、离合器摩擦表面温度与外锥体温度场 1.不稳定导热过程离合器滑摩产生的热量使摩擦付表面温度升高,继而传到整个摩擦付
Modern marine friction clutches are designed not only with static design to meet the requirements of maximum torque transmission but also with dynamic design to control the temperature rise and stress caused by thermal load within the allowable range. In this paper, a dry tapered hyperelastic friction clutch is taken as an example. According to the thermoelastic theory and the finite difference principle, a method for calculating the dynamic temperature field and stress field of a marine friction clutch is proposed, which provides the conditions for the dynamic design of the clutch. First, the friction surface temperature of the clutch and the outer cone temperature field 1.
