摘要：

In order to study the temperature characteristics of aviation high power density wet friction clutch under the action of oil cooling, the thermal characteristics analysis model of the waffle groove wet friction clutch was established based on the computational fluid dynamics (CFD) method;the calculation method and application method of the heat flux density on the friction pair in the wet friction clutch were studied.Using the heat flow coupling method, the heat dissipation effect of the oil was considered, and the oil and temperature distributions on each friction pair in the clutch were analyzed.The research results showed that the uneven distribution of oil on the steel disk and friction disk caused uneven temperature distribution on the steel disk and friction disk.The temperature distribution on different steel disks and friction disks was affected by the oil distribution on the disks and the thermal conductivity of the disks, showing different temperature distribution laws. © 2022, Editorial Department of Journal of Aerospace Power.
