| 摘 要： | 用位置敏感探测器检测振动信号，与传统的加速度传感器相比，提高了系统检测精度，缩短了响应时间，减小了时滞对隔振性能的影响．建立了振动主动被动复合控制系统的动力学模型，设计制作了实验装置，并对隔振性能进行了实验测试．实验结果表明，振动主动被动复合控制兼有主动控制和被动控制的优点，具有良好的隔振效果，在频率10～1500Hz基础激励范围内，动传递率低于20％．

| Abstract: | Position sensitive detector(PSD) was adopted as the vibration detection sensor,which,compared with an acceleration transducer,can improve measurement precision,reduce the response time,and minimize the influence of time delay.The dynamic model of active and passive compound vibration control was derived.An experimental apparatus was designed,and the performances of vibration isolation were verified by experiments.Results suggest that the compound control gains the advantages of both active control and passive control.The ratio of vibration transmissibility is less than 20% when the frequencies of input signals are 10 to 1 500 Hz. |
