Description

technical field [0001] The invention relates to a generalized loading device, in particular to a parallel six-dimensional force sensor calibration device. Background technique [0002] At present, the calibration of force sensors mostly adopts the loading method of applying standard weights. This method can only calibrate the sensor in one direction, and is not suitable for compound loading and calibration of multi-dimensional force sensors, and this method is not suitable. Calibration of large range sensors. Although the applied load can be amplified under a certain loading weight through the principle of leverage, this method does not have high loading accuracy for the sensor, and the calibration of the anisotropic torque of the sensor, especially the multi-dimensional force sensor, is inaccurate, unsystematic, and not suitable. Generalized loading and calibration of large size sensors. Contents of the invention [0003] The purpose of the present invention is to provi...
