Study of Tip Deflection on a Copper-Steel bimetallic Strip by Fuzzy Logic and ANSYS Static Structural

Abstract

Steel and copper are the most widely used materials around the world. In this work, the tip deflection of a fixed-free support Copper-Steel bimetallic strip is simulated using Fuzzy Logic and ANSYS Static Structural. Copper-steel is a very popular bimetal and is used widely in different fields of technology. For Fuzzy simulation, Tip Deflection Fuzzy Logic Controller (TDFLC) is designed with three inputs as T.Diff, Thickness, and Length while T.Deflection as output. For input values of T.Diff (278 °C), thickness (1.4 mm) and length (120 mm) TDFLC generates T.Deflection of 12.8 mm with an error of 1.59%. For real-time simulation, the geometry of dimension 120×7×1.4 mm is designed by ANSYS. At the temperature difference of 278 °C, ANSYS results are 12.8 mm with an error of 1.59%. The results concluded that the tip deflection is inversely related to thickness while in direct relation with both temperature difference and Length of bimetal.
