【摘要】 本文在文献资料和实验的基础上，分析了转子不平衡产生的原因及危害，论述了各类不平衡转子的平衡方法，在此基础上根据生产实践的需要，以MCB-980通用硬支承平衡机为基础，以刚性转子为研究对象，分析各种测量方法尤其是瓦特表测量系统的优缺点及力测量动平衡机系统的信号特点，建立了一种新的刚性转子双面动平衡的数学模型，分析了求取动不平衡量大小和相位的原理，在此基础上开发了一种以工控机为主机的硬支承动平衡机微机化测量系统。系统采用了先进的硬软件技术，努力实现大批量、高精度、易操作和低成本的总体目标。同时还进一步设计了该微机系统的良好界面菜单结构，系统可以根据不同用户的要求，选择合适的支承、显示、校正、补偿方式和留言服务功能等。更多还原

【Abstract】 This paper firstly analyses the various reasons and dangers caused by unbalanced rotors according to information and experiments, after these, different balancing methods for different types of unbalancing rotors were discussed. On the basis of the theory that discussed above, the paper analyses different types methods of measuring especially wattmeter measuring system and character of signals of hard bearing dynamic balancing system and designs a hard-bearing microcomputer-based measuring system for different types of hard bearing dynamic balancing machines. Using advanced technology both in hardware and software of the modern, this system aims to reach the general goal of great mass, high precision, easy-to-operate and lows cast. In order to meet the needs of different users, this system is designed to be applicable under different supporting, displaying and compensating modes. Also, this system features averaging over tine & runs, redistribution of correction data between multi-planes, data/screen printing, message to next operator service. Finally a better interface and menu of the system discussed above is contrived and the result can be steady on screen and easily get without errors.更多还原
