Abstract

This paper presented a new approach of multi-axis force/moment measurement with non-axis coupling. A floating plate of rectangular hexahedron was completely floated with flotation method. The compound force and compound moment along coordinate axes X, Y, Z were obtained by measuring the changes of pressure differential in every group air nozzle pressure cavity. The air nozzles were placed symmetrically at the turning of the floating plate, and placed symmetrically in both sides of up and down, left and right, frond and back of the floating plate with 2 in a group. The formulas to calculate the combined force and moment in the sensor along the coordinate axes X, Y, and Z were presented, and the measurement precision of the air floating force-measuring system were studied and analyzed. A set of air-suspending six-axis force/ moment sensor was developed based on this research. After experimental verification of the result of theatrical research, the result showed: the force measurement method proposed by this paper can measure compound force and compound moment along coordinate axes X, Y, Z act on the floating plate and there is no coupling during the measurement and the measurement precision is higher than multi-axis sensor based on strain gauge
