Six dimensional crossing decoupling RSS acceleration transducer

Abstract

This invention disclose a 6 dof perpendicularity discoupling RSS acceleration transducer, the characteristic: inertial platform (1) connect with fixed platform (3) by 3 groups branched chain, each group branched chain composed by two branched chain (2). master rod of each block branched chain mutualy plumb in space, fixed platform connect with each group branched chain mutual perpendicular in space;inertial platform (1) is regular polyhedron inertia or roundness quality piece; each strip branched chain (2) has two elasticity sphere deputy ( 2 - 1) and one turn deputy ( 2 - 4). On top of turn deputy perch (2-3), there has elasticity turn deputy ( 2-4) that cross section is rectangular. Two surface of elasticity turn deputy (2 - 4) adhibit strain gauge (2 - 5). The elastomer in this invention quite right respond to corresponding parallel institution mechanical model, has normal and adult design philosophy, thus theoretical design error is smallness;owing to institution model possess favorable discoupling quality, the sendout synthesizing and decomposition algorithm are simplicity, response quickly; And has good isotropy.

Description

technical field [0001] The invention relates to a six-dimensional orthogonal decoupling RSS acceleration sensor for measuring three-dimensional linear acceleration and three-dimensional angular acceleration in space. It belongs to the technical field of automatic control. Background technique [0002] Acceleration sensors are generally composed of elastic bodies, strain gauges (or other components) and conversion circuits. When there is an acceleration to be measured, the elastic body will be deformed by the inertial force or moment of the mass block, and the corresponding linear acceleration or angular acceleration will be obtained through the strain gauge and the conversion circuit. At present, the acceleration sensor technology below three dimensions is relatively mature, and there are many products on the market. For the six-dimensional acceleration sensor, its elastic body structure is complex and lacks a mature design theory. Therefore, the technical difficulty in de...

AI Technical Summary

Problems solved by technology

For the six-dimensional acceleration sensor, its elastic body structure is complex and lacks a mature design theory, so the technical difficulty in developing a six-dimensional acceleration sensor is to find an elastic body structure that is easy to design and manufacture

At present, for the six-dimensional acceleration sensor, the double cross beam structure is mostly used. The acceleration sensor of this structure has poor isotropy, high coupling degree, and a large amount of calculation in design and use.
