摩擦学系统中的摩擦常常引起振动。这项探索性研究要回答的问题是,是否有可能扭转这一过程——通过向系统中引入与摩擦力平行的振动能量来影响和控制机械系统中的摩擦。潜在的应用包括防止闲置轴承冻结的方法,非常低的摩擦轴承和滑动,非常高的摩擦制动器,以及提高加工难加工材料的可行性。将测试两个主要的频率范围——测试系统本身的特征振动频率和接触区摩擦力的特征频率。应注意消除任何外来振动。如果这一初步实验研究的结果令人鼓舞,将计划进一步的理论和实验工作。
英文摘要
Friction in tribological systems often causes vibrations. The question to be answered by this exploratory study is whether it is feasible to turn this process around - to affect and control friction in a mechanical system by introducing vibrational energy into the system, in parallel with the friction forces. Potential applications include methods for keeping idle bearings from freezing up, very low friction bearings and slides, very high friction brakes, and improved feasiblity of processing difficult materials. Two main frequency regimes will be tested-the characteristic vibrational frequency of the test system itself and the characteristic frequency of the friction forces in the contact zone. Care will be taken to eliminate any extrinsic vibrations. If the results of this initial experimental study are encouraging additional theoretical and experimental work will be planned.
