将控制技术运用到拱型结构的振动控制中．运用单点和多点控制方法，将主动控制力表示为位移、速度和加速度的线性函数，在频域内探讨了拱型结构某些关键部位的加速度频率响应随地面运动频率变化情况，研究了主动控制力参数对加速度响应的影响，并对带有主动控制装置的拱型结构在随机激励作用下的响应进行了分析，结果表明选用速度的线性函数主控力形式可明显降低结构加速度响应，控制力的最佳位置与要控制的振型有关
The control technology is applied to the vibration control of the arch structure. Using the single-point and multi-point control methods, the active control force is expressed as a linear function of displacement, velocity, and acceleration. In the frequency domain, the frequency response of acceleration of some key parts of the arch structure with the ground motion frequency is studied, and the initiative is studied. The influence of the control force parameters on the acceleration response and the response of the arched structure with active control device under random excitation are analyzed. The results show that the linear control function of the selection speed can significantly reduce the structure acceleration response and control. The best position of force is related to the mode shape to be controlled
