A reasonable combination of structural parameters can improve the natural frequency of the cantilever beam weighing sensor elastomer and can improve the response characteristics of the sensor. The parameterized 3 D model for the cantilever beam load cell is established through the Solidworks parameterized modeling software. In order to achieve parameter transmission without lossing

a seamless connection between the Solidworks and the ANSYS Workbench is established. On the basis of modal analysis on the cantilever load cell

based on the optimized design function module of ANSYS Workbench

optimized calculation and analysis are carried out

by calculating and analying on sensitivity of the relevant parameters to the optimization target and the input parameters to the optimization target to determine the best optimization plan. Through the comparison with the original plan

the result shows that the natural frequency of the optimized sensor is increased by 2. 47 %

achieve the goal of optimization.
