“…Vehicle body panels are made out of thin sheet metal and, thus, have a very low bending stiffness. Hence, it has become common practice to increase the stiffness of these thin body panels by introducing ribs, stiffeners or beads [1,2,3]. A recent audit of different brands of automobiles currently in production shows that the body panels are designed with a wide variety of beading configurations, ranging from elliptical beads (domes) to criss-crossed swages, as illustrated in Fig.…”

A quite cabin is always a preferred choice of the customer. Powertrain acts as a source for many noise and vibration problems in a passenger car. Transmission plays a major role in modulating the power from engine to the drive train and is exposed to a high vibration and noise environments. Hence design of transmission for low vibration & noise is need of the hour. This paper attempts to perform a comparative study of 6 housings of different design of a two-wheel drive passenger car to evaluate the vibration performance and Noise radiation characteristics by using FEM (Finite Element Method) & BEM (Boundary Element Method) & finite element analysis techniques. The authors also try to put forward a layout comparison study for the housings and conclude what design is best suited for better NVH whine performance in view of vibrations & sound radiation. These indicative results from this paper can be referred by the design & analysis engineers during early product development of the transmission.
