Embodiment Construction

[0014] Fig. 1 is an embodiment disclosed by the present invention, is connected with 3 groups of branch chains between inertial platform (inertial mass) 1 and fixed platform 4, each group of branch chains is made up of left side branch chain 2 and right side branch chain 3, The structures of the left and right branch chains (2, 3) are the same but their poses are different. Each branch chain is made up of upper connecting rod 2-1, elastic ball pair 2-2, branch chain main rod 2-3, rotating auxiliary rod 2-4, elastic rotating pair 2-5 and lower connecting rod 2-7. There are elastic ball pairs 2-2 at both ends of the chain main rod 2-3, and the elastic ball pairs 2-2 are rigidly connected with the upper connecting rod 2-1 and the rotating auxiliary rod 2-4 respectively, and the rotating auxiliary rod 2-4 is connected with the lower The rod 2-7 is rigidly connected, the upper connecting rod 2-1 and the lower connecting rod 2-7 are respectively connected with the inertial platform ...

Abstract

This invention disclose a 6 dof perpendicularity discoupling RSS acceleration transducer, the characteristic: inertial platform (1) join with fixed platform (3) by 3 groups branched chain, each group branched chain include Left Side branched chain ( 2) and right side branched chain ( 3) left and right branched chain have same structural phase but different gesture. Branched chain at fixed platform (4) submit circle symmetry disposal. Each strip branched chain (2) has two elasticity sphere deputy (2 - 2) and one elasticity turn deputy ( 2 - 5). on top of turn deputy perch (2-4), there has elasticity turn deputy ( 2-5) that cross section is rectangular. two surface of elasticity turn deputy (2 - 5) adhibit strain gauge ( 2 - 6). 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 the technical field of automatic control, in particular to a six-dimensional RSS acceleration sensor for measuring three-dimensional linear acceleration and three-dimensional angular acceleration in space. 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 or other detection elements and conversion circuits. [0003] 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, due to the complexity of the elastic body structure, there is a lack of mature design theory, so th...
