Abstract

The present invention discloses a generalized force and force moment measuring device of the multiple-degree-of-freedom parallel mechanism in a spring structure format. The measuring device includes a multiple-degree-of-freedom parallel mechanism, a transverse spring, a diagonal drawn spring, a fixed external frame and a connection mechanism; the fixed external frame does not move relatively to the base of the parallel mechanism, and the connection mechanism is connected to the moveable platform of the multiple-degree-of-freedom parallel mechanism in a rigid and moveable mode and is connected to the fixed external frame through a plurality of springs. The present invention provides a compact, ideal and succinct measuring device of force and force moment, and the device can be used for measuring the generalized force and force moment of all kinds of multiple-degree-of-freedom platforms and for loading.

Description

technical field [0001] The invention relates to force and moment testing equipment, in particular to a generalized force and moment testing device of a multi-degree-of-freedom parallel mechanism in the form of a spring structure. Background technique [0002] The current generalized force and torque test device is basically a six-dimensional force sensor test. In the research of generalized force and moment test device, the commonly used generalized force and moment test device with Stewart platform structure adopts spherical pair form or elastic spherical joint, or improves its structure. The structural form and mechanism are complicated, the processing accuracy and installation accuracy are high, and the price is expensive. And other forms of generalized force and moment test devices for three vertical rib structures, cylindrical, double ring, four vertical rib structures, box structures, cross structures, cylindrical, double-headed, three beam structures, and eight verti...
