Six-dimensional force sensor of eight-beam structure

The invention discloses a six-dimensional force sensor of an eight-beam structure. The six-dimensional force sensor is characterized by comprising a stress disc, a shell, a base, an elastic beam, a plug connecting piece and a plug. The stressed disc is connected with a force application device through a screw hole; the plug connecting piece is installed on the outer side face of the shell; the plug is fixed on the plug connecting piece; a base boss of the base is mounted in the shell; the elastic beam comprises a disc beam body and eight supporting beams; the disc beam body is connected with the stressed disc; stress concentration holes are formed in the eight supporting beams; the two sides of the center of the stress concentration hole in each supporting beam are each provided with two strain gages; the elastic beam is mounted on the base. The sensor has the advantages of being high in output precision, simple and compact in structure, simple in process, few in strain gauge, high insensitivity and decouplin
