Elimination of Truck Cab Vibration Induced by Torque Variations of a 4-Cycle 6-Cylinder Diesel

This case history explains a practical test procedure which led to the successful solution of a cab vibration problem through the development of a new engine front mounting arrangement. It also substantiates the importance of considering the dynamic properties of materials used in vibration isolation. The new engine mount provided the required freedom for transverse vibratory displacement of the engine, thereby keeping much of the engine vibration out of the frame rails and the cab.
