【摘要】 研究带有扭转弹簧两端铰支轴向运动梁的横向振动。利用边界条件得到系统的频率方程,通过数值方法解出系统的前两阶固有频率随轴向速度变化的情况,并导出了系统的前两阶复模态函数。讨论了固有频率与模态函数、轴向速度及弹簧弹性系数的关系。更多还原

【Abstract】 Vibrations of an axially transporting beam are investigated.The boundary conditions considered may be assumed to be on simple supports with torsional springs at both ends,which is an appropriate assumption to the real constraints.The first two natural frequencies and the relevant modal functions are obtained numerically and the contributions of the transporting velocity and the torsional spring coefficient are discussed.更多还原
