Torque Sensors Calculation Software

Abstract

The problem of torque control is relevant in many technological processes today. In order to better measure torque, it is appropriate to use special sensors instead of indirect control methods. The system of a circular contactless magnetoelastic torque sensor has a number of advantages over existing devices, such as strain gauge or other types of magnetoelastic sensors. However, each technological process needs to design its own magnetoelastic sensor with unique characteristics. Calculation of these characteristics is a long and complicated process, due to long equations with a large number of coefficients, which are dependent on conditions of the technological process. Output value variability, in addition, depends directly on selected parameters. It means that calculation shall be repeated in order to receive more suitable output values. The authors propose the special program that makes it easier to calculate the characteristics of this devices. This program selects the necessary values of coefficients automatically, in addition to solving the equations. It also allows users to vary different parameters of the device according to the conditions, with subsequent printing the output values on the screen. As the result, using this program, a rapid, accurate and automated calculation of a torque control device becomes possible.
