Abstract:

A correlational research of an oil orbit of dual clutch automatic transmission model was done by using the ANSYS-Fluent software. Firstly, CFD simulation of the oil orbit was done and the mass flow rate of each nozzle was treated as the evaluation indicator, whose results were consistent with the experimental results. Secondly, on the basis of that, the influences of oil temperature variation on the distribution of the mass flow rates of these nozzles were studied. At last, the injected situation of the oil orbit and the influence of splashing fluid were simulated in the overall CFD model of transmission when they were at the case of complex oil and air two-phase flow. And the rationality for the design of lubrication system of oil orbit was verified.
