Abstract

This paper describes a transfer path analysis method used to analyze the low frequency noise and vibration contribution of suspension and engine mounts caused by second order engine vibration. This transfer path analysis method is capable of removing transmitted forces from other paths (residual forces) besides the main path at a particular degree of freedom. Compared to the conventional methods, results from this analysis method had improved accuracy with respect to vehicle measurements. From the results of the transfer path analysis performed by using this method, frequency range and contribution by the suspension paths for low frequency noise and vibration are clarified.
