Topology Optimization of Traverser for Rail Coach Shifting Applications

In the present work, a traverser is built based on available dimensions. So analysis is carried out on existing structure for better product development based on finite element solutions. The results for stress and deformation are captured. The initial weight of the structure is observed to be around 46 tons. Later the structure is optimized based on the visual observation of the stress distribution in the member, the corresponding elements are removed using Hypermesh software and the same structure will topology optimization is analyzed for structural strength conditions. The results shows increase in the stress of the assembly as well as components. But a weight reduction is observed from initial 46 tons to 37 tons. This reduction helps in lesser inventory along with lesser maintenance. Generally higher material requirements reduce the efficiency of the system by increasing procurement, maintenance and handling expenses. Also higher weight increases the mechanical inertia of the parts and large driving mechanism is required for its operation. So finite element analysis is carried out to improve the problem by virtual simulation.
