Study on Accurate Strength Analysis of Blade Wheel in Vehicular Hydraulic Retarder Based on Sequential Coupling Method
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. The results showed that incipient fault of safety existed in the root of rotor blade, and the method of accurate strength analysis was credible and facilitate on the platform of commercial code of ANSYS/Workbench.
