• In the present study, a higher- and lower-order truncated modal and coupled structure-acoustic finite-element sensitivity analysis is performed to determine the rate of change of vibration responses of the body panels and sound pressure level at the position of the ear of a passenger/driver, and an inverse multi-objective optimization problem based on the structural synthesis method and pseudo-inverse method is solved to determine the required minimum changes of the design variables from the baseline design parameters to attain the selected design response in a shortest path. It is found that the structural synthesis method and the pseudo-inverse method converge to the solution when the step size at each iteration level of the optimization process is kept small.
