一篇有关车内振动传递路径分析的文章。英文摘要：By new advancements in vehicle manufacturing, evaluation of vehicle quality assurance has got a more critical issue. Today noise and
vibration generated inside and outside the vehicles are more important factors for customers than before. So far several researchers
have focused on interior noise transfer path analysis and the results have been published in related papers but each method has
its own limitations. In present work, the vibration transfer path analysis and vibration path ranking of a car interior have been
performed. As interior vibration is a source of structural borne noise problem, thus, the results of this research can be used to
present the structural borne noise state in a vehicle. The proposed method in this paper does not need to disassemble the powertrain
from the chassis. The procedure shows a good ability of vibration path ranking in a vehicle and is an effective tool to diagnose the
vibration problem inside the vehicle. The simulated vibration spectrums in different speeds of the engine have a good compliance
with the tested results; however, some incompatibilities exist and have been discussed in detail. The simulated results show the
strength of the method in engine mount optimization.
