초록
The styling of automobile wheels and their effect on vehicle appearance has increased in importance in recent years. The wheel designer has been given the task of insuring that a wheel design meets its engineering objectives without affecting the styling theme. The wheel and tire system is considered as a vehicle component whose dynamic modal information of the tire/wheel system are employed in the modal synthesis model of the vehicle. The Modal characteristics of a Automobile wheel play an important role to judge a ride comfortability and quality for a Automobile. In this paper, the modal characteristics of a Al-alloy and steel wheel for Automobile are studied. Natural frequency, damping and mode shape are determined experimentally by frequency response function method. Results show that wheel material property, size and design are parameter for shift of natural frequency and damping.
Abstract

The Modal characteristics of a Automobile wheel play an important role to judge a ride comfortability and quality for a Automobile. In this paper, the modal characteristics of a Al-alloy and steel wheel for Automobile are studied. Natural frequency, damping and mode shape are determined experimentally by frequency response function method. Results show that wheel material property, size and design are parameter for shift of natural frequency and damping.
