介绍了一种用于消除镗轴颤振的兰切斯特阻尼器。套管轴自由振动的衰减率被认为是颤振的重要性。本文分析了带有粘滞耦合兰彻斯特阻尼器的单自由度系统的自由振动，给出了确定最佳耦合的图表。讨论了空气薄膜的阻尼特性。
A Lanchester damper for eliminating chatter of boring quills is shown. The rate of decay of free vibrations of the quill is found to be of importance in chatter. The free vibrations of a single-degree-of-freedom system with a viscously coupled Lanchester damper attached are analyzed, yielding a chart from which the optimum coupling can be determined. The damping characteristics of thin air films are discussed.
