In-orbit high-precision calibration device and method for multi-dimensional force sensor

The invention relates to an in-orbit high-precision calibration device and method for a multi-dimensional force sensor. The device comprises a fixed beam, an elastic beam, a sliding ruler, and a calibrating cone. The fixed beam and the elastic beam are fixed together through bolts penetrating mounting holes. The calibrating cone is fixed in the through hole in one end of the elastic beam. The sliding ruler can freely side on the fixed beam and the elastic beam. The effective length of the elastic beam can be changed by moving the sliding ruler so as to calibrate a force value of the multi-dimensional force sensor. The force applied to the multi-dimensional force sensor is read through a pointer on the sliding ruler, pointing to a mark line on the fixed bema.
