Abstract

A novel structure of hyperstatic parallel six-component force sensor based on the Stewart platform was proposed

and its theoretical dynamics analysis and finite element simulation were performed. The structure feature of the sensor was described in comparison with the classical Stewart platform-based six-component force sensor. By using the finite element method

the elastic dynamics theoretical model of the sensor was established based on the conditions of displacement consistency and force balance. According to this model

the numerical analysis was carried out

and the variety relationship curves between the natural frequencies and the structural parameters are plotted. By using a ANSYS software

the finite element model of the sensor was built to analyze the vibration modal of the sensor

and the natural frequencies and the vibration modes were obtained. The research results establish the foundation for the further dynamics analysis and synthesis of the sensor and the dynamic optimization design of the sensor.
