The vibration transmission paths in a sport-utility vehicle with a frame structure were used to evaluate the coupled vibration of each vibration transmission link. This method was based on the transmission path of an “engine-powertrain mount system-frame-vehicle body suspension-body-driver seat rail,” and the research objective was to improve the vibration characteristics of the cab. This coupled transfer path analysis combined analysis and experiment to establish the vehicle vibration transmission path model and a finite element simulation model. With this method, the vibration level of the driver’s seat rail was reduced and engineering practice was effectively used to improve the vibration characteristics of the cab. This method was applied to a framed SUV cabin.
