Study on the analysis method of the cab vibration transfer path

Transfer Path Analysis (TPA) is a diagnosis based on noise and vibration engineering test, mainly used in processing the excitation source - transmission path - in response to system problems, finding out the key path influence. As an approach of comprehensive noise and vibration issues, TPA help setting performance targets for each of the key components, which can help engineers determine the root cause of problems in the early stages of design [1].
