摘要

摘要: 基于Coriolis加速度和Lagrange应力公式，利用Newton定律得到了运动带的横向振动运动方程．运用多尺度法得到了传送带系统主参数共振的近似解．分析了调谐参数、带的横截面积、黏弹性参数、轴向速度不仅影响非平凡稳态响应的幅值，并且影响其存在区域，揭示了一些新的动力学现象．

Abstract: Based on Coriolis acceleration and Lagrangian strain formula,the transverse vibration sys-tem of convection belts equation generalized was derived by Newton.s second law .The method of multiple scales was applied directly to the governing equations,and approximate solution of primary parameter resonance of the system was obtained.The detuning parameter,cros-s section area,elastic and viscoelastic parameters,and an axial moving speed have a significant effect on the amplitudes of steady-state response and their existence boundaries.Some new dynamical phenomena were re-vealed.
