Reconfigurable parallel multidimensional force sensor

Abstract

A reconfigurable parallel multidimensional force sensor mainly comprises a loading platform, an elastic connection rod A, an elastic connection rod B, transverse cantilever beams, vertical cantilever beams, reinforcing beams, a lower platform, a support plate, a regular octagon support plate, swallow-tail support plates and strain foils. Sensor structure decoupling is realized through the arrangement mode of force measurement branches, and force decoupling performance is good; through different combination modes of the strain foils, measurement of three forces and moments can be realized conveniently; and through automatic detection and identification of software, corresponding measurement models are selected, and mission-requirement-oriented measurement models are established, that is, measurement demand for some force or some moment based on task is realized. The multidimensional force sensor directly targets to multitask or key task multistage complex actual measurement requirements, can be suitable for task requirements under different environments, can be connected with the outside world conveniently through the upper and lower circular ring structures, and is more suitable for various application occasions.

Description

technical field [0001] The invention relates to the field of sensor design and manufacture. Background technique [0002] The sensor is a tool for the mechanical system to obtain external information. It can perceive the measured physical quantity and convert it into an output signal according to the corresponding change law. The six-dimensional force sensor can measure three force components and three torque components at the same time, and can detect the force direction of the mechanical system and the magnitude of the force changing in real time. Today, high-precision, high-sensitivity, and multi-task measurement requirements Multi-dimensional force sensor has become a research hotspot. [0003] In the research of the six-dimensional force sensor, the structural design of the force-sensitive element has always been the key core issue. The important properties of the force sensor, such as stiffness, sensitivity, and resolution, are closely related to the structure of the ...
