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.

当机器系统发生不受控制的振动时，可能会出现严重的问题，导致部件和系统磨损和最终故障，以及噪音问题。这项研究设想了一种减少振动的方法以及与之相关的问题。它是一个理论和实验相结合的项目，研究由固定的平板或相对运动的物体之间的薄层流体所产生的阻尼的测量。这方面的初步工作表明，这种减震方法在常规治疗无效的低频下可能非常有效。这项工作在本质上是基础的，但可能适用于有效设计轻量、低频的减振处理。
