Embodiment Construction

[0009] As shown in the drawings, the present invention includes a generalized loading mechanism 5 based on a parallel six-degree-of-freedom mechanism composed of a fixed platform 7 of the loading mechanism, a joint hinge 8 , six sets of parallel linear actuators 6 and a movable platform 9 of the loading mechanism. The fixed platform 7 of the loading mechanism is installed on the ground or other fixed planes, and a set of six-dimensional force sensor 4 is installed on the movable platform 9 of the loading mechanism. The loaded object fixing mechanism 2 is installed coaxially with the loading connection mechanism 3 below, and the support frame 1 is installed on the ground or on other fixed planes.

[0010] The working principle of the present invention is as follows:

[0011] The present invention fixes the loaded object 10 on the support frame 1 through the loaded object fixing mechanism 2, and six sets of linear actuators 6 installed in parallel with joint hinges 8 on the gene...

Abstract

The invention discloses a kind of generalized loading system based on parallel six-freedom platform. The system includes linear performer based on platform fixed by loading system, joint hinging, six sets of parallel linear performer, and generalized loading mechanism made up of parallel six-freedom mechanism. The loading mechanism fixing platform is set on the ground or other fixed plane, there has a six-dimension force sensor on the platform, the other surface of the sensor is connected with the loading connection mechanism, sets the loaded object fixing mechanism under the supporting frame with the same axis to the loading connection mechanism, the supporting frame is set on the ground or other fixed plane. The invention is a kind of compound loading system which provides a compact and ideal integrating project.

Description

technical field [0001] The invention relates to a loading system, in particular to a generalized loading system based on a parallel six-degree-of-freedom platform. Background technique [0002] The current loading system and load simulation system are basically loaded by single-degree-of-freedom hydraulic cylinders or hydraulic motors, and due to structural reasons, although various compensation methods have been adopted, none of them can fundamentally eliminate redundant forces. Contents of the invention [0003] The purpose of the present invention is to provide a generalized loading system based on a parallel six-degree-of-freedom platform, which provides a compact and ideal integration solution for a multi-degree-of-freedom force and moment composite loading system. [0004] The technical solution adopted by the present invention includes: a generalized loading mechanism based on a parallel six-degree-of-freedom mechanism...
