摘要
基于参数激励作用下黏弹性传动带横向振动运动方程,应用多尺度法得到1/2次亚谐-主参数共振的近似解。分析了黏弹性参数、调谐参数、轴向速度等参数对稳态响应幅值和存在区域的影响,揭示了黏弹性带的动力学现象。
Based on the viscoelasticity driving belt of transverse vibration equations under the action of parametric excitation,by using the method of multiple scales,the approximate solution of the 1 /2 subharmonic- primary parametric resonance equations is obtained. The influence of the viscoelasticity parameter,detuning parameter and an axial moving speed on the amplitudes of steady- state response boundaries is analyzed. Some new dynamical phenomena are revealed of viscoelasticity driving belt.
