Abstract

By using sphere pair with unilateral constraint, the limbs of the proposed pre-stressed six-axis sensor must be under pressure in the measurement process, so prior to measurement, a certain preload must be applied to the sensor. The viable limbs’ number of the pre-stressed six-axis force senor is determined by using convex theorem. By solving the static equilibrium equation of sensor, the reacting forces on limbs are divided into two parts: the particular solution is generated by the external force, while the homogeneous solution is only concerned with the pre-tightening force. The number of parameters to be determined in homogeneous solution is decreased by linear transform, and the method for determining the pre-tightening force is derived to make all the limbs compressed when it is subjected to the expected range of external force. A numerical example to determine the pre-tightening force of the force sensor is performed. The numerical example results show that the force on limbs can always maintain positive value with the appropriate pre-tightening force, which proves the correctness of the theoretical analysis and the validity of the sensor structure.
