Vibration control of a realistic coupled powertrain and frame system is analytically and computationally studied using a combination of active and passive mounts. Actuators are placed in the powertrain paths for active control, and passive mounts are employed such that the powertrain roll motion is dominant using the torque roll axis motion decoupling concept. To facilitate this study, a new 24 degree of freedom mathematical model for a coupled powertrain and frame is developed with versatility where passive only, active only, or combined active and passive powertrain paths can be selected. Active control forces are defined as constant, real valued amplitudes to counteract the dominate powertrain roll motion. Alternate path models are then quantitatively compared based on the global powertrain motion magnitudes. It is found that superior vibration control is achieved with combined paths, provided all powertrain paths are aligned with the torque roll axis coordinates. Additionally, successful control is dependent on which paths are selected as a combination of active and passive mounts, dictated by the interaction between active control forces and the passive system dynamics.
