摘要

针对多移动质量耦合作用下柔性梁的振动响应进行研究分析。根据柔性梁振动理论,考虑移动质量间相互运动与柔性梁弹性振动之间的耦合作用,建立了多移动质量-柔性梁系统的振动方程。采用时变力学系统数值求解方法,对多移动质量以不同运动形式作用下柔性梁系统的振动响应进行求解分析。计算结果表明:移动质量间相互运动的形式不同,梁的振动效果不同;与单个移动质量叠加作用相比,多移动质量间耦合作用下的梁的振动效果呈现显著的不同。

Abstract

The vibration response of the flexible beam under the coupled multi-moving masses with variable speeds is studied. Based on the vibration theory of the flexible beam, the vibration model of the multi-moving masses-flexible beam system is established. The interaction among the moving masses and the coupling effect between the motions of moving masses and the vibration of the flexilbe beam are considered in this model. The numerical simulation is conducted by solution method of time-variant mechanical system. Results show that the vibration response of the flexible beam is different under different forms of motion among the moving masses, and the coupling effect among moving masses enhance the vibration response of the flexible beam.
