AI Technical Summary

Problems solved by technology

It can realize any six-dimensional force loading in space, and the calibration device and the sensor to be calibrated can be tested once clamped. It has the advantage of compact structure, but when any six-dimensional force is loaded, six electric push cylinders must act together, so More electric push cylinders are required, the layout is difficult, and the synchronization control is complicated

[0005] In summary, the existing six-dimensional force sensor calibration device still has the problems of small calibration loading force range, low calibration force and moment accuracy, many loading force sources required, and complex structure of the calibration loading device.
