Numerical Analysis of a New Pressure Sensor for Measuring Normal and Tangential Stresses in the Roll Gap

The paper is in polish. Orig. title: "Analiza numeryczna nowego czujnika do pomiaru nacisków i naprê¿eñ stycznych w procesie walcowania" A new strain gauge sensor for measuring normal and tangential stresses in the contact arc of a rolling process has been designed and constructed. The complicated load history of the sensor results in complicated deformation patterns of it, and consequently the calibration procedure of the sensor should cover a wide range of loading cases, and would thus be very difficult and time-consuming to carry out. As an alternative to this, a FEM simulative experiment has been per-formed to prove that a newly developed analytical method applied on the strain-gage signals enables the extraction of the normal and tangential load distribution in the arc of contact. For this purpose special software has been designed. The results of the numerical experiments have veri-fied the reliability of the suggested method of analysis. Apart from the direct measurement in the rolling process, the software is well suited for optimization of the shape of the transducer.
