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 of development lies in finding an elastic body structure that is easy to design and manufacture
At present, the six-dimensional acceleration sensor mostly adopts a double cross beam structure, the acceleration sensor of this structure is poor in isotropy, and the calculation amount of the design is also large

Embodiment Construction

[0012] 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, and 3 groups of branch chain inertial platforms (inertial mass) 1 and fixed platform 4 form a circle Evenly distributed, each group of branch chains is composed of left branch chain 2 and right 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 branch chain main rod 2-1, elastic mobile pair 2-2, elastic ball pair 2-4 and lower connecting rod 2-5, and branch chain main rod 2-1 and lower connecting rod 2-5 There is an elastic ball pair 2-4 at the end, and the elastic ball pair 2-4 is respectively connected with the inertial platform (inertial mass) 1 and the fixed platform 4 by interference fit; the elastic moving pair 2-2 has a pair of parallel plates, and the Paste 4 strain gauges 2-3 on the surface.

Abstract

This invention disclose a sort of 6 dof paralleling structure sps acceleration transducer, refer automatic control engineering region. The characteristic: inertial platform (1) join with fixed platform (4) 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 has two elasticity sphere deputy (2 - 4) and one elasticity remove deputy (2 - 2). elasticity remove deputy ( 2 - 2) has a pair parallel plate, on the surface of parallel plate has pasted strain gauge ( 2 - 3). 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 parallel structure SPS 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 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, so the technical difficulty of development...
