In order to develop four-column force sensors with high dynamic performance, based on the Mechanism Analysis Method, stablished the natural frequency model of the four-column elastomer and mastered the design method to improve the natural frequency. The correctness of this method is verified by SolidWorks simulation and Standard Hammer Experiment. The results show that the natural frequency has a great relationship with the structural of four columns, and summarized the improvement methods of structural parameters conducive to improving the natural frequency of four-column sensor. Increasing the length parameter or width parameter of the cross section of the four-column sensor and reducing the height parameter of the four columns are conducive to improving the natural frequency of the four-column sensor.The results also point out that improving the material properties of sensor can also improve the natural frequency of sensor.Increasing the elastic modulus of the material of the four-column sensor, reducing the density of the material of the four-column elastomer can further improving the natural frequency of the four-column sensor.
