The Nonlinear Response of Train Suspension System under Poisson Excitation
The vibration between wheel and rail when train moves.The vibration will be even greater and more prone to derailment and affecting ride comfort especially when there are obstacles in the seams of the two tracks or tracks.Wheel-rail coupling stochastic nonlinear dynamical model will be created based on the analysis of vehicle - orbit coupling idea,considering Poisson excitation as acontinuous function.Solving the system’s random nonlinear dynamic responsibility under the Poisson pulse by using improved perturbation method.
