Study on the Impact of Structural Parameters on the Vibration of Automobiles

As people’s needs in life increase more and more, automobile has become the means of transport that is being popularly used in their daily activities. In addition to cost and form, ride and handling is among the important criteria for modern automobiles; and the vibration level of a vehicle directly affects its smoothness level. Nowadays, digital simulation is being widely used in studying the mechanical system of an automobile, more than that, the simulation process has proven its preeminence as it can depict the nonlinear system when simulating the vibration level of an automobile. Basing on mentioned requirements, the research team has simulated the oscillation system of an automobile while taking nonlinear factors into consideration by setting reasonable structural parameters with a view to ensure smooth ride and handling for coaches. In this article, they will clarify the impact of structure on the smoothness of coaches and how to select a suitable structure for each type of coach.
