Abstract
The present invention relates to a holding force testing device which belongs to the field of applied mechanics and mechanical design. The present invention specifically relates to a testing device which can be used for testing the magnitude of holding force as well as testing the spacial two-dimensional force. Application fields relate to sports, medical care, civil use, etc. The present invention is mainly formed by connecting circular-arc cylindrical outer cases 1, 2 and two rectangular spring steel plates 3, 4, and gaps are mutually left between the outer cases 1, 2 and the spring steel plates 3, 4 so as to meet the maximal force testing range. Four force sensors 5, 6, 7, 8 are arranged in the present invention, wherein the force sensors with different phase positions form a spacial two-dimensional force testing system. When any point of the device is held, the force sensors can spatially decompose the force under the action of external force. The effective component force is then extracted. The magnitude of the holding force of any point can be reflected by synthesis. The device realizes the functions of testing holding force in multiple directions as well as testing the magnitude of spacial two-dimensional force for the first time.
