Pallet is the key power transmission component of weighing sensor error calibration device,and satisfying the stress and strain limiting condition is the basis to guarantee the quality of calibration. This paper builds 3D model by UG based on the pallet of weighing sensor error calibration device,and obtains the distribution of stress and deformation of the pallet with finite element analysis software and method. Then the paper exercises optimal design under ANSYS Workbench according to analysis results and gets the relationship between input parameters and stress,strain and quality. And it selects the optimal input parameters on this basis. The final result shows that optimization method could decrease by about 7% quality of the pallet.
