轴向运动梁横向振动固有频率微分求积法研究

A Numerical Investigation into Natural Frequency of Transverse Vibration for an Axially Moving Beam

根据动力学分析和边界条件推导出轴向运动梁的系统特征方程,利用微分求积法对本征方程离散,计算出梁横向振动的固有频率,并数值模拟了梁运动速度和刚度对固有频率的影响。

The transcendental equation is established based on the dynamics analysis and boundary condition.The natural frequencies of transverse vibration of beams are numerical calculated via the differential quadrature method.The effects of axially moving speed and flexural stiffness are examined respectively as other parameters are fixed.
