Abstract

The invention, which belongs to the technical field of parallel mechanisms, in particular relates to a parallel six-dimensional acceleration sensor. The parallel six-dimensional acceleration sensor based on a spring sliding pair is composed of a spherical mass block, a base and a plurality of elastic telescopic rods. First ends of the plurality of elastic telescopic rods are connected with the spherical mass block and are distributed along the equatorial plane of the spherical mass block respectively; and second ends of the plurality of elastic telescopic rods are connected with the base. Pressure sensors are fixedly arranged in the elastic telescopic rods and are opposite to telescopic ends of the elastic telescopic rods; the telescopic ends and the pressure sensors are connected by elastic connecting members; and the pressure sensors are used for detecting stress changing values generated by the elastic telescopic rods. With the parallel six-dimensional acceleration sensor, a technical problem of low sensitivity caused by the high stiffness of the existing six-dimensional acceleration sensor is solved.

Description

technical field [0001] The invention belongs to the technical field of parallel mechanisms, and relates to an acceleration sensor, in particular to a parallel six-dimensional acceleration sensor. Background technique [0002] In recent years, with the development of artificial intelligence, the market has higher and higher requirements for the intelligence, precision and space size of mechanical devices. Six-dimensional acceleration sensors are widely used in the field of mechanical engineering, and have a large market demand in inertial navigation systems, dexterous robot wrist joints, aerospace, vehicle instability warning, and vision systems. [0003] Compared with the series mechanism, the parallel structure has higher stiffness, load capacity and accuracy, and is widely used in the research of six-dimensional acceleration sensors. In the existing six-dimensional acceleration sensor, the high stiffness of the parallel mechanism makes the output stress and strain value s...
