摘要本文旨在以向量空间关联性的方法来分析两个相近频率模组的关系。 - Taking the bending stiffness , cable sag and cable inclination into consideration , the space vibration control of the cables using the visco - elastic dampers in cable - stayed bridges is investigated by joining the center difference method and the state space strategy . both the maximum modal damping ration and the optimal damper size are obtained , then the practical suggestions are proposed for the design of the dampers . the space nonlinear vibration equations of the cable - damper system are derived , and a new hybrid method for solving the cable - damper system is presented by combing the newmark method and pseudo - force technology
综合考虑了拉索抗弯刚度、垂度的影响，研究了粘弹性阻尼器对斜拉桥拉索的空间振动控制，联合中心差分方法及状态空间法，得出了拉索面内、外振动各阶模态可能达到的最大阻尼比及相应的最优阻尼器系数，并对斜拉桥拉索的阻尼器设计提出了参考建议：考虑拉索抗弯刚度、垂度及几何非线性，导出了索-阻尼器系统的空间振动非线性方程组，结合newmark方法及伪力( pseudo - force )方法，创新地提出了求解非线性方程组的杂交方法，根据拉索-阻尼器系统的阻尼特性，在各种荷载作用下，对索-阻尼器系统的非线性瞬态振动响应进行了研究，从系统响应的角度更加直接地验证了阻尼器的控制效果。
