Inspired by the manufacturing process of switch rails for railway turnouts, a method for the optimization of switch rail profile geometry is presented. The switch rail profile geometry is parameterized with four design variables to define a B-spline curve for the milling tool profile, and two design variables to prescribe the deviation from the nominal vertical path of the milling tool. The optimization problem is formulated as a multi-objective minimization problem with objective functions based on the contact pressure and the energy dissipation in the wheel–rail contact. The front of Pareto optimal solutions is determined by applying a genetic type optimization algorithm. The switch rail profile designs are evaluated by simulations of dyn...
