A Novel Three Degree-of-freedom Force Sensor

摘要：

In this paper, a novel strain-gauge-based three DOF force sensor,which can provide 3 axis force vector for controlle by measuring the force real time with wide force measurement range,low coupled interference and relatively low cost,is developed.Firstly, the system structure of the force sensor which contains the sensig element and the sampling circuit with USB interface is introduced.The distribution of strains and the design of Hilton Bridge Circuit have been described in detall.Then, a finite element analysis for the elastic body of the sensor is made.The paper calculates a fixed quantity of static couple under three components with the reasonable finite element computation model, and appraises the rationality of the structural design.Finally,based on the and interfernce errors of the three DOF force sensor are calculated.
