Abstract: One of the important themes in this age of conservation of resources and energy is the reduction of vehicle weight, which helps to improve running performance, but which generally produces undesirable effects in terms of noise and vibration. To reduce noise and vibration inside a car and reduce its weight at the same time, it is now necessary to reexamine the conventional method of reducing noise and vibration, and deal with the problem by using a more advanced method. What is important with regard to noise and vibration inside the car is the noise and vibration of the drive train, and many useful studies on the drive train have been reported in Japan. Drive train vibration can roughly be classified into bending vibration and torsional vibration. Generally, they are combined, and may have nonlinear characteristics. All this makes the problem quite complex. This report introduces a selection of previously announced, important study results which have been edited to enable the reader to understand the outline of the Japanese studies on drive train. The report covers the following: drive train vibration analysis (linear and nonlinear vibrations); engine surge and drive train vibration; and differential gear noise and drive train vibration.

Keywords: vehicle design; drive train; vehicle noise; vehicle vibration; noise pollution control; vehicle weight reduction; vibration analysis; bending vibration; torsional vibration; engine surge; differential gear noise.
