拉索端部弹性约束振动控制研究(Ⅱ)——试验验证
Study on vibration control of cables with elastic end restraint(Ⅱ):Experimental verification
【摘要】 在索端沿轴向设置弹性约束,对拉索振动轴向被动控制进行了试验研究。研究了支座移动对拉索振动频率的影响;验证了弹性约束对拉索振动的减振效果,讨论了阻尼系数和弹簧刚度对减振效果的影响;最后验证文献[10]中理论研究的正确性。
【Abstract】 The experimental research is conducted to study the axial passive control of cable vibration by setting an elastic end restraint at one support of the cable in the axial direction.The influence of support motion on the natural frequency of cable vibration is presented.Then the damping effect of elastic restraint is verified and the influence of the damping coefficient and the spring stiffness on the damping effect is discussed.Finally the theoretical study [10] is verified to be accurate.
