Rail Pinned-Pinned Vibration Influence Factor And Control Method

When a train traveling on the rail with a certain speed, because of the irregular of the contact surface, wheeltrack collide occurs, then, a kind of vibration called "Pinned-Pinned" vibration occurs and radiate a lot of noise. Research on it's influence factor and it's control method is important, to find a way to control the "Pinned-Pinned" vibration, and post a way to decrease the rail vibration is of vitally important.Now, the way to control vibration mainly through three kinds of ways, sound source control, vibration and sound spreading control and control of its material and structure. Rail is made up of certain material and structure, so research the vibration style of the rail, and focus on the rail's vibration attribute to find some way to control it's vibration is of vital important.This article is based on the finite element theory and focus on the rail "Pinned-Pinned" vibration, we build a model in the software ANSYS to analysis it's vibration attribute, while build a rail- absorber system to analysis it's damping attribute while the system is forced by the shock excitation, we change the related parameter of the model to research it's exactly response. At last we are trying to find what is going on in the rail-absorber system when we change the related parameter and to summarize its discipline.This article mainly focus on the influence factor of "Pinned-Pinned" vibration, to summarize it's law for further research.
