项目摘要
This project aims at establishing a collaborative research program between Purdue University and Precise Corporation to develop state-of-the-art technologies for high- speed spindles. The research efforts will focus on developing comprehensive analytical and empirical models as well as conducting critical experimental studies for new high spindles with hybrid ceramic bearings. The study will determine the potential benefits of ceramic bearings in terms of dynamic and thermal characteristics as well as durability. Analytical modeling will include lubricant effects and fully three-dimensional thermal expansion in addition to bearing geometry, bearing material, preload, preloading method, external load, operating conditions and spindle shaft configuration to determine dynamic and thermal characteristics. Experimental test rigs will be developed to determine friction and temperature characteristics of hybrid ceramic bearings under operating conditions. The research will establish speed-load regions for advantageous application of hybrid ceramic bearings, and thus will lead to the establishment of a scientific and technological basis for high speed spindles with ceramic bearings that can provide full benefits of high speed machining. The analytical modeling tool and experimental database to be developed from this joint effort will provide a systematic tool to help achieve optimal design of high speed spindles to avoid a costly failure of expensive machines.
该项目旨在建立普渡大学和Precise公司之间的合作研究计划,以开发最先进的高速主轴技术。 研究工作将集中在开发全面的分析和经验模型,以及进行关键的实验研究,为新的高主轴与混合陶瓷轴承。 该研究将确定陶瓷轴承在动态和热特性以及耐用性方面的潜在优势。 分析建模将包括润滑剂效应和全三维热膨胀,以及轴承几何形状、轴承材料、预载、预载方法、外部载荷、操作条件和主轴配置,以确定动态和热特性。将开发实验测试装置,以确定混合陶瓷轴承在工作条件下的摩擦和温度特性。 该研究将为混合陶瓷轴承的有利应用建立速度-载荷区域,从而为陶瓷轴承高速主轴的科学和技术基础的建立,可以提供高速加工的全部效益。从这一共同努力中开发的分析建模工具和实验数据库将提供一个系统的工具,以帮助实现高速主轴的优化设计,以避免昂贵的机器出现代价高昂的故障。
