摘要
研究了微型斯特林制冷机的振动主动控制问题 ,设计了一种全新的减振器 ,即用直线电机推动一个弹簧振子系统 ,在控制系统的反馈控制下产生控制力 ,来抑制制冷机的振动 ,该方案的使用使制冷机的振动水平减小了一个数量级。
Based on analysis of the active vibration control for miniature Stirling refrigerator, it designs a new kind of vibration absorber. In order to provide the correct force as the request of the control system and restrain the vibration, this absorber uses a linear motor to push the mass-spring system. The result shows that the vibration amplitude of the Stirling refrigerator is only about one tenth of the original one without the system.
