Developing fuel saving technique are needed for preventing global warming and energy resource issue in automotive industry. Engine downsizing is one of the fuel saving technique. It can attain miniaturization of an engine and maintain an engine performance. However, it increases in cost and torsional vibrations occur and cause serious noise and vibration problem. Therefore, a centrifugal pendulum absorber which utilizing dynamic vibration absorber theory was developed for torsional vibration. In previous study, dynamics characteristics were solved by using the equation of motion that was modeled to a spring-mass system in a torsional vibration system. Although it was considered to inertia and rigidity of each component, the structure and mechanism movement were not considered. Therefore in this study, an analytical model with multi-body dynamics considering them was developed and conducted to verification of damping effect by experiment. For the results, it was clarified that centrifugal pendulum absorber can reduce torsional vibration. Key Words: Analytical model, Torsional Vibration, Vibration Control, Simulation
