LIGHT-DUTY TRUCK CAB ARCHITECTURES FOR ENHANCED NOISE, VIBRATION, AND HARSHNESS CHARACTERISTICS

摘要

Many recent developments in light-duty commercial truck technology have resulted from the need to improve fuel economy without sacrificing the structural integrity of the vehicle. This paper documents part of an effort to reduce weight through the use of innovative design architectures. Specifically, a number of crossmember architecture concepts were developed for the cab floorpan of a light-duty truck. The floorpan is a key structural component of any vehicle, providing a significant contribution to noise, vibration, and harshness parameters such as stiffness and normal modes. Finite element concept models of the baseline cab and concept cabs are used to show that architectural changes in the crossmembers can significantly reduce the weight without compromising structural performance.
