WebMay 3, 2016 · Wedge suspensions are critical systems for three-piece bogies. This paper proposes a methodology to optimize wedge suspensions using white-box suspension models, dynamic simulations of railway vehicle systems, parallel multi-objective Particle Swarm Optimization (pMOPSO), and parallel multi-objective Genetic Algorithm (pMOGA). WebSemi-analytical solutions demonstrate that the predesigned shunting circuit under linear host system assumption does not only work effectively but also makes the stability of the host system worse. To suppress the resonant peak of the host system efficiently, the particle swarm algorithm is applied to determine the proper shunting circuit of the PSVA.
