The Real Case of Powertrain Mounting Design for Trucks 2002-01-3508

This paper presents the method applied in the development of an optimized powertrain mounting assembly for a Light Truck Diesel or Pick-up application. The focus of this optimization is to improve the vibration insulation and consequently improve the NVH (Noise and Vibration Harshness) quality of the vehicle. The paper describes the basic mounting design and manufacturing constraint, the simulation modeling basis, inputs required to perform the computational simulation, the experimental work required, also the method used to determine the center of gravity and rotational inertia of the powertrain and a general mounting tuning strategy. The experimental results for an optimized version are also presented and compared to the original one.
