変動移動面速度下の強制摩擦振動 : 三次元摩擦特性の場合の断片線形近似による解析

抄録

Self-excited forced vibrations with solid friction of a block lying on a moving surface of nonconstant speed stated already in the previous report are treated theoretically, using a piecewise linear approximation method in case of cubic friction-velocity characteristics. The motions of a block in the system are studied for two cases. Namely, the first is the case in which the maximum static friction is equal to the kinetic friction without slipping and the second is the case in which it differ from it. The steady-state vibrations are obtained with regard to the stick and the slip motions of the block. The distributions of various types of these vibrations occurring in the system are shown in several figures and the amplitude curves of the displacement waves are described against the frequency ratio Ω and the speed of moving surface Y₀/Y.
