Abstract

Ride comfort and idling performance are conflicting low-frequency noise and vibration issues in vehicle development. A convenient index for evaluation of these two phenomena at the design stage was formulated by defining the degree of coupling in a simple numerical expression representing the characteristic matrix based on a physical coordinate system. The degree of coupling was used for performance evaluations of idling and ride comfort in CAE impulse forced response simulation and in an actual vehicle, with good correlation. It was ascertained that this method could be used effectively as a design tool for performance evaluations of powertrain mount layouts in designing total vehicle performance.
