Operational Deflection Shapes & Resonance Analysis Using
Road Simulator 2019-26-0323
In today’s competitive world to stay in the commercial vehicle business, technological advancement is vital. Understanding the various operation modes of a vehicle considering the vibration becomes essential for developing a vehicle free from failures. ODS analysis is a method which is used to visualize the vibration pattern of a vehicle when influenced by known external operating forces. They provide very useful information for understanding and evaluating the behaviour of the vehicle.
This paper discusses about the experiments carried out on School bus. It details the process of data collection at varying frequency input, understanding the modes at various frequencies, identifying the resonant frequency of various components, understanding the comparison between road inputs and resonance frequencies and the transfer of vibration (Transmissibility) from one component to another.
