| 摘 要： | 为了研究在高速工况下液黏调速离合器的摩擦副表面油槽结构对油膜流场传动特性的影响,设计了一种新型的C形槽摩擦片。利用SST k-ω湍流模型,通过流体动力学仿真软件Fluent对C形槽和径向槽摩擦副所构成的油膜流场进行数值模拟,并获得其流场传动特性。研究表明,摩擦副在高速运转条件下,C形槽的温升要低于径向槽而且油槽处有明显的冷却效果,当输入转速持续提高时,C形槽的温升趋于平缓;随着输入转速的提高,C形槽所传递的转矩呈线性增长,在输入转速相同的前提下,相比于径向槽,C形槽所构成的流场不仅温升小而且可以提供更大的转矩。

| Abstract: | In order to study the influence of friction surface oil groove structure on the transmission characteristics of oil film flow field under high speed working conditions, a new type C groove friction plate was designed. Then, the SST k-ε model was used to simulate the flow field of the oil film of c-shaped slot and radial groove by the fluid dynamics simulation software. What's more, the flow field transmission characteristics were obtained. Research shows that the friction pair under the condition of high speed, the rise of temperature of the c-shaped slot is lower than the radial groove and oil cooling effect obviously, when the input speed continues to increase, the rise of temperature of the c-shaped slot leveling off. With the improvement of the input speed, c-shaped slot torque transmission by a linear growth, in the input speed of the same premise, compared with the radial slot, c-shaped slot of flow temperature rise not only small but also can provide greater torque. |
