돌기승월에 의한 타이어 벨트부의 동적 변형 해석에 관한 이론적 고찰

In general, the pattern of external force acting on the tire belt is found by enveloping experiment. However analytic approach to establish mechanical relationship is necessary in the enveloping problem. In this study, the tire belt is considered as a cantilever beam which has vertical stiffness and bending stiffness under tensile force. Then we focus on the deformation of the belt by moving load. Deformation in dynamic state analysis is larger than that in static state. Also, deformation of the belt is considerably large at extremely high speed, 120㎞/h. It probably results from impact characteristic in very short time.
