RIA: Mechanics of Self-Pressurized Foil Bearings

点击翻译按钮获取中文摘要

This study will develop an improved model of the head-tape interactions in high-speed magnetic tape storage mechanisms. In particular, the coupled dynamics of the rapidly moving flexible tape and the air foil bearing, which develops between the tape and the recording head, will be modeled and a closed form solution will be developed. The model is expected to provide information about pressure distribution, head-tape separation and other technologically important parameters.
