Submicro-cattle thrust vector testing method and device

The invention relates to the technical field of precision measurement, and provides a submicron cattle thrust vector testing method and device.The submicron cattle thrust vector testing device comprises a frame support erected on a base and a double-shaft cantilever mechanism, a first cross beam is arranged on the top of the frame support, and the double-shaft cantilever mechanism is connected to the center of the first cross beam; a dangling type double-shaft structure is formed; the micro-thruster mounting rack is used for mounting and fixing the sub-micro cattle magnitude micro-thruster and adjusting the position in the measurement process; the double-shaft electromagnetic execution machine and the double-shaft displacement sensor are used for measuring the displacement change of the micro-thruster mounting rack in two orthogonal directions in the horizontal plane and the thrust vector of the sub-micro-cattle magnitude micro-thruster; and the data processing module is used for reading the working current o
