Shape Optimization of ‘S’ Type Load Cell Using Finite Element Method

Abstract - In this work ʹSʹ type load cell is considered for shape optimization by using finite element method. The shape optimization is carried out to minimize the weight of ʹSʹ type load cell without exceeding allowable strain. The intention of the work is to create the geometry of ‘S’ type load cell to find out the optimum solution. FEM software ANSYS is used for shape optimization of ‘S’ type load cell. If the stress & strain values are within the permissible range, then certain dimensions are modified to reduce the amount of material needed. The procedure is repeated until design changes satisfying all the criteria. Experimental verification is carried out by photo-elasticity technique with the help of suitable instrumentation. Experimental results are compared with FEM results.
