Objective Most existing studies on catenary system dynamics simulation are based on the assumption that the pantograph base has only longitudinal degrees of freedom, neglecting the influence of carbody vertical vibration induced by wheel-rail excitat

Particle dampers (PD) can be embedded in structures fabricated via selective laser melting (SLM) because the raw powder (particle diameter : several tens of micrometers) remains in closed spaces during SLM. However, most PD studies have focused on co
