To master the conditions of rigid rotor balancing, to understand the process of calculating the amount of rotor imbalance. Second, the existing basic principle of dynamic balance theory, research and applications, including the correction to the heavy, with heavy disk correction and manual correction of dynamic balance scale. One major study to re-type correction to the drilling, but is weighted three-point method, respectively weight method, 4 weight method and the reverse point weight method. And rotor balancing process designed to determine the total residual rotor unbalance and the unbalance of the total allocation to the remaining number of correction plane is the key, and by choosing to re-weight method or methods to balance and correct imbalances in the rotor. Key words: rotor balancing, balancing accuracy, residual unbalance, dynamic balance, weight method  目录 1绪论1 1.1刚性转子动平衡技术现状1 1.2动平衡测试技术的现状及发展4 1.3动平衡校正理论的现状及发展6 2动平衡校正理论的基本原理9 2.1基本概念9 2.2刚性转子动平衡理论基本原理9 2.3动平衡校正理论基本原理15 2.4本章小结19 3刚性转子动平衡工艺的设计20 3.1转子动平衡工艺的设计20 3.2动平衡的校正25 参考文献27 致谢28 转子动平衡的研究与设计 PAGE 48
