Abstract
<div class="section abstract"><div class="htmlview paragraph">Usually conventional iterative methods of optimization will consume more time to optimize the given design. Mostly, it becomes very difficult if multiple loads are acting on the structure contradicting each other. CAE based optimization technique becomes more useful in such cases to optimize the given design and achieve weight reduction. Optimization methods offers guidance to expedite solutions, resulting in a substantial reduction in product development time. Nowadays, optimization became inevitable part among the virtual validation processes of design in industries.</div><div class="htmlview paragraph">A wide range of optimization methods have been effectively employed in the design of tractor components, especially mounting brackets, chassis and skid housing for the development of off-road vehicle. Based on the design stage, various optimization techniques were followed i.e. Topology, size and shape. Depending upon the available analysis time & Design freedom, determines the type of optimization approach to be used. In case, the design is already finalized at the stage of mass production, only minimal design modifications were allowed and very less time will be given to optimize the design by using size optimization. In other case, if the design is in the middle of the development stage where relatively more freedom is available to perform topology optimization which is based on the base CAD model. Optimization approach was used to reduce the weight by removing an unnecessary thickness/material while maintaining the sufficient strength. Finally, optimized design has been verified through CAE analysis. Some of the optimized components were tested and implemented successfully. 84% and 96% strain correlation were achieved in the optimized model between test and CAE.</div><div class="htmlview paragraph">This paper explores and utilizes the Topology, Size and Shape optimization methods to achieve an optimized design of various tractor components for different load applications and in turn to reduce the cost/weight of the components.</div></div>
