Study on Ride Comfort of Non-Linear Vehicle Vibration System

Abstract:

Based on the mathematical model of non-linear rubber bearings under the condition of random excitation and time domain model of road roughness, the 11-dof vibrant model for vehicle was built with considering the non-linear rubber bearings. Then the influence of the rubber bearings on ride comfort was simulated under the condition on the B-class road profile by different speed as the random input. The result shows that the way of modeling the vibrant model is feasible, and the influence is not a simple monotone function, especially in the barycenter acceleration of vehicle body.
