Reliability Analysis for the Automobile Gasoline Economizer of the One-way Gear Devices on the 3D Contact Analysis

Three-dimensional elastic contact model of the automobile gasoline economizer of the one-way gear devices is analyzed on the base of FEM. The work condition is calculated, and the stable stress distribution, strain distribution and the deformation of the outer ratchet, inside core and pawl are obtained. With the FEA analysis results, the intensity reliability of each part is checked based on maximum shearing stress criterion and criterion of the strain energy density corresponding to distortion. The results indicate that the device is safety.
