Vibration Reduction in Passenger Vehicle by Optimization of Propeller Shaft Design

In Passenger segments, vehicles floor vibration is one of the major cause which leads to discomfort for passengers. There are several locations for vibration, one of the location is Floor of the bus where passengers will feel the vibration directly while sitting on the seats and while standing on the Gangways. So acceleration levels in passenger segment should be as per AIS 153 standard. The objective of this paper is, of all the available causes for vibration, we will discuss about the middle floor vibrations raised by Propeller shaft and how to mitigate the problem by various focused design proposals on Propeller shaft. Here, we will be reviewing the Bus segment which has a Double Piece Propeller shaft design configuration.
