Effects of Different Oil Inlet and Outlet Distribution on Hydraulic Retarder 2014-01-2498

The paper studies on the basis of VOITH R133-2 hydraulic retarder, the inlet and outlet structures of the oil passage on the stator are rearranged, which are made a more uniform structure distribution. In order to find out the characteristics of this kind of structure arrangement. The flow passage models for two different structures are established, and the internal flow field characteristics are studied by using the CFD (Computational Fluid Dynamics) method. The flow rules of the internal oil, the distribution of pressure field and velocity field as well as output braking torque are obtained. The results show that rearranged structure retarder has a more uniform pressure distribution and a lower output braking torque than original structure retarder. And the simulation verifies the effectiveness of simulating true flow by CFD in hydraulic retarder flow field and conduct retarder design and structure optimization.
