Summary:

The main emphasis for a commercial vehicle design which was focused on fuel-economy and durability does not fulfill the increasing customer expectations anymore.Commercial vehicle designers need to focus on other vehicle aspects such as steering, ride comfort, NVH, braking, ergonomics and aesthetics in order to provide car like perception to truck, bus drivers and passengers during long distance drives.Powertrain mounting system must perform many functions. First and foremost, the mounting system must maintain and control the overall motion of the powertrain, to restrict its envelope reasonably, thereby avoiding damage to any vehicle component from the potential impact. This requires the mount to be stiff.Second the mount must provide good vibration isolation to have a comfortable ride to the vehicle occupant. This requires the mount to be soft.These requirements contradict each other and hence a suitable "Tradeoff" is needed for achieving the rigid body mode targets for a comfortable vehicle ride and also restraining the powertrain motions within vehicle packaging constraints
