Abstract

The invention discloses a kind of generalizing loading test system based on parallel multi-freedom mechanism. The system includes the generalizing system based on six-freedom parallel mechanism, and the loaded mechanism based on multi-freedom mechanism. The loading mechanism fixing platform is set on the ground or other fixed plane, the loading mechanism moving platform sets a set of six-dimension force sensor, the other surface of the sensor is connected with the loading connection mechanism, there sets the loaded object fixing mechanism under the supporting frame with the same axis to the loading connection mechanism, the lower part of the loaded object fixing mechanism is connected to the loaded mechanism fixing platform, the loaded mechanism moving platform is connected to the loading connection mechanism, the supporting frame is set on the ground or other fixed plane. The invention provides a kind of compact and ideal integral project.

Description

technical field [0001] The invention relates to a loading test system, in particular to a generalized loading test system based on a parallel six-degree-of-freedom mechanism. Background technique [0002] The current loading system and load simulation system are basically loaded by single-degree-of-freedom hydraulic cylinders or hydraulic motors, so the test systems are also single-degree-of-freedom, and there is no multi-degree-of-freedom loading test system. Contents of the invention [0003] The purpose of the present invention is to provide a generalized loading test system based on a parallel six-degree-of-freedom mechanism, which can be used for loading tests of multi-degree-of-freedom force and moment loading systems, and provides a compact and ideal system for the generalized loading test system. Integrated solutions. [0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: include the generalized loadin...
