Summary:

Under the action of strong wind, the aerodynamic behavior of a locomotive at high velocity changes significantly, which declines the safe operation of the vehicle. Using the shape of a locomotive used in India, the aerodynamic characteristics of a locomotive are investigated with the help of the computational fluid dynamics (CFD) numerical simulation method, which is based on a variation of aerodynamics force and moment with wind speed, train speed, and nose shape. Moreover, determining a correlation between different design parameters and the aerodynamic drag requires complicated algorithms. In this paper, the objective is to optimize the locomotive drag and aerodynamics force using the multi-objective optimization method (MOOM). In this technique, the evolutionary algorithm, configuration parameterization method, and computer simulation are used The Pareto optimal results are determined by the calculation of 10th generation evolutionary with 512 individuals. The outcome of the analysis indicates that both the objectives are effectively optimized, which suggests that the optimization technique used in this research work efficiently enhances the optimization performance and matches the practical aspects
