Abstract

In modern technological environment, the conventional methodology of design cannot compete the modern trends of computer aided engineering techniques. Continuously the research is going on for new innovative design in the engineering field. To build a highly optimized product is the basic requirement of today’s global market. All around efforts were put forward in this direction. Various software professionals and technologies have developed various design packages. It is a challenging task to shape optimize 'S' type load cell with best functional requirements and at lowest weight. In this project an attempt is made to model an ‘S’ type load cell and optimization of the same using the finite elements analysis software ‘ANSYS’. A simple model of ‘S’ type load cell is considered for FEM modeling and optimization. This paper illustrates the model of ‘S’ type load cell before optimization and finally obtained optimized model. Using Photo-elasticity technique, results are crosschecked which gives results very close to FEM technique. With the aid of these tools the designer can develop and modify the design parameters from initial design stage to finalize basic geometry of Load Cell.
