A Study on Housing Design in Conception of Dynamic Characteristics

This paper descrived housing design in conception of dynamic characteristics. The vibration and noise in power train system of automobile are important on the environment matter. The vibration caused by meshing teeth of gear is transmitted to the gear box faces through shafts and bearings. Shape of housing is used different radius of curvature(R=0 to 80 mm). The velocity responese, sound power and radiation efficency on the surface of gear box are calculated. The sound power and radiation efficency are compared with different radius of curvature.
