当发生不受控制的振动时， 机器系统，造成部件和系统磨损， 故障以及噪音问题。 这项研究设想了一种方法， 减少振动和与之相关的问题。 它 是一个理论和实验相结合的项目， 测量夹在两层之间的薄流体层产生的阻尼 无论是静止的板块还是相对运动的物体。 初步 这方面的工作表明，这种阻尼方法可能非常 在常规治疗失败的低频下有效。 的 工作是基本的性质，但可能适用于 轻质、低频阻尼处理的有效设计。

Serious problems may arise when uncontrolled vibrations occur in machine systems, causing component and system wear and ultimate failure, as well as noise problems. This research envisions a method of reducing the vibrations and the problems associated with them. It is a combined theoretical and experimental project dealing with the measurement of damping resulting from thin fluid layers trapped between either stationary plates or objects in relative motion. Preliminary work in this area suggests that this method of damping may be very effective at low frequencies where conventional treatments fail. The work is fundamental in nature but potentially applicable to the effective design of lightweight, low-frequency damping treatments.
