Abstract

The invention provides a double-*-shaped shaft type force sensor and a method thereof. The force sensor comprises a force bearing cylinder, wherein the force bearing cylinder is internally provided with two excitation magnetic cores, the excitation magnetic cores are composed of excitation magnetic poles which are distributed in a cross manner, the excitation magnetic poles are respectively wound with excitation coils, induction magnetic cores are respectively installed at two sides of the two excitation magnetic cores and between the two excitation magnetic cores, each induction magnetic core is composed of two pairs of induction magnetic poles which are distributed in a crossed mode, and induction coils are wound on the induction magnetic poles respectively. The sensor is suitable for complex use conditions of a force sensor in electro-hydraulic lifting control of a high-horsepower tractor, the sensitivity of the sensor is improved through bias superposition of a magnetic field, and the sensor can also be used for heavy load measurement in other similar environments.

Description

technical field [0001] The disclosure belongs to the technical field of force sensors, and in particular relates to a double Pozier type force sensor and a method thereof. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] In the electro-hydraulic lifting control process of high-horsepower tractors, soil resistance is one of the main control signals. As the main signal receiving device of the electro-hydraulic lift control, the force sensor plays an irreplaceable role in it, and is one of the core components of the electro-hydraulic lifter. [0004] The performance of the force sensor directly affects the quality of the hanging agriculture. The working environment of the force sensor requires it not only to have a large heavy load and bearing capacity, but also to have a good linear output under the premise of slight strain. , which has a ...
