Plume force/torque measuring system based on piezoelectric effect. Online calibration of testing system is one of serious problems which are needed to solve. In view of vertical structure of plume force/torque test system

calibration system as core with hydraulic pressure source coordinated by standard force sensor is designed.Calibration platform which can remotely operate

on line calibrate real-time and real time adjust. Analyze load method for six dimensional force calibration and relationship between loading force and force of sensor. Six dimensional force loading mechanical model is established. Static calibration experiment is carried out in test system

obtain six-axis force/torque sensor linear fitting equation of straight line. Experiments show that the six axis force calibration system owns a great many advantages of stability and reliability

high precision

simple operation

little impact on environment

and so on.
