摘要
超声振动带来的减摩效应具有减摩效果好、控制方便、高效节能且无污染等优点,得到了国内外学者较为广泛和深入的研究,并已成功应用于提高加工质量、减小机械摩擦及改善仪器测量精度等领域。近几年这项技术也逐渐引起了气动领域相关学者的兴趣,研究表明超声振动对气缸摩擦力的改善有明显效果,同时为流体传动与控制领域研究学者提供了一种全新的摩擦与运动控制手段。该研究将从超声减摩的起源与发展入手,对气动领域中超声减摩的核心问题及未来研究的前景予以阐述。
The friction reduction by ultrasonic vibration has the advantages of satisfying friction reduction ratio, eas- y control, high efficiency, and non-pollution. It has got wide and deep investigated by global researchers, and been successfully implemented in reducing mechanical friction, improving machining qualityand apparatus accuracy. During recent years, this technology has aroused the interest in pneumatic field, and it reveals that there is a good friction reduction effect when the ultrasonic vibration is introduced to pneumatic cylinders. Meanwhile, it provides a novel method in controlling friction and motion for the scholars on fluid power and control. This paper will discuss the core pneumatic issues and the outlook related to the ultrasonic friction reduction.
