Based on theory of fluid-solid interaction (FSI), a three dimensional finite element computational model of blade wheel in a vehicular hydraulic retarder was built considering accurate fluid pressure and centrifugal stress with unidirectional FSI method, and viscous numerical simulation of computational fluid dynamics and then strength analysis were implemented, and the reliability of blade wheel was verified.
While for CFD and CSD analysis, the computational grids were quite different and nodes of them can not be coincident generally, so the calculation information can not be exchanged directly, then the automatic information mapping mechanism should be adopted based on ANSYS/Workbench platform involving CFX and mechanical modular.
According to the cyclosymmetric of wheels, a group of passages with one rotor and stator passage was selected as CFD computational model shown in Fig.3, and grid and boundary conditions were applied to it.
Fig.3 Model group of CFD computation with rotor and stator passages When hydraulic retarder works, especially applied with centrifugal stress rotor load is larger than stator load throughout, so the strength of rotor should be paid more attention to, and for the cyclosymmetric feature of rotor blade wheel of hydraulic retarder, solid geometry model and computational FEA model of 1/20 rotor blade wheel were shown in Fig.4.
The constraints were defined as follows: (1)periodic symmetric restrain was applied on slicing planes of 1/20 model; (2)displacement restrain was applied at hub of rotor wheel; (3)fluid pressure load derived from CFD analysis was applied on the pressure and suction surface of blade; (4)rotating speed of 2200 r/min was applied to the whole rotor wheel model, while that of stator wheel is zero.

This study implemented numerical simulations by establishing a fluid dynamic model to evaluate the intensity of the shear stress under various rotating speed and diameter of the shaker.
Simulation setup.
The simulation was carried out with a commercial computational fluid dynamic (CFD) software.
Rotating speed and diameter of the shaker were two independent variables in the simulation.
