Abstract
Structural optimization was important nowadays in getting the optimum design and usage of the material use, where size optimization is part of it. This research is focusing on the application of size optimization on steel wheel rim. Existing steel wheel rim dimension was measured and Finite Element Analysis (FEA) was done to get actual dimension and mechanical properties (stresses), as baseline data. CAD modelling on steel wheel rim was done using Pro-Engineer/Creo 1.0. One structural element was selected to be optimized. Then optimization program was generated using MAPLE to get optimum value (size). Steel wheel rim will be re-modelled with optimum size to get optimum design. FEA was done again on optimized steel wheel rim to compare with actual steel wheel rim data. Optimized steel wheel rim was showing better in mechanical stress with optimum size (minimize the weight and volume).
