Strain type six-dimensional force transducer

Abstract

The invention discloses a strain type six-dimensional force transducer including a bottom cover, a base, a circuit board, elastic bodies, and a top cover. The bottom cover is connected with the bottom surface of the base, the circuit board is arranged inside the base, the four elastic bodies are uniformly distributed in the base, the outer side ends of the sensing elements of the elastic bodies are connected with the base, the inner side ends of the sensing elements of the elastic bodies are connected with the top cover, and the top cover is supported on the base through the elastic bodies. The strain type six-dimensional force transducer can better eliminate the inter-dimensional coupling due to the adoption of the plurality of elastic bodies and reasonable strain gauge bridge scheme design, and the strain type six-dimensional force transducer can have high rigidity and good sensitivity through the elastic bodies in a special structure.

Description

technical field [0001] The invention belongs to the technical field of sensors, and relates to a resistance strain sensor capable of simultaneously detecting three-dimensional force and three-dimensional moment. Background technique [0002] The six-dimensional force / torque sensor is a newly developed sensor in the force sensor, which can convert multi-dimensional force / torque signals into electrical signals at the same time, and can be used to monitor force and torque with changing directions and sizes. With the development of aerospace, modern robots and other fields, there are more and more applications of six-dimensional force sensors. [0003] In the strain gauge multi-dimensional force sensor, the elastomer structure is the main factor affecting the performance of the sensor. According to the structural form of the elastomer, the elastomer can be divided into a one-piece structure and a composite structure. A monolithic structure is generally a single geometric shape...
