Abstract

The finite element analysis method was used to analyze the modal and random vibration acceleration PSD of analytical balance package to obtain the stress distribution nephogram and the acceleration power spectral density response curve.The multi-objectives optimization design on cushioning pads were performed to obtain the cushioning structure of low cost and high property.The finite element model was established via Solidworks,and the dynamic simulation was done via Ansys Workbench.The deformation and vibration properties of the package in the transportation process were analyzed to find out the weak points of the package.The Optimal design of response surface was conducted the cushioning pad with acceleration,maximum deformation and mass of the package as the objective function.After response surface optimization analysis,the performance of the package was improved.Through the simulation analysis and the optimization design on the analytical balance package,the structure size of cushioning pad can be improved,the breakage rate of the product during transportation can be reduced,and the cushioning structure can be lightweight.
