摘　　要：在大量实验数据的基础上,探索多跨转子动平衡首次试重的最佳位置。在一阶临界转速之下和一阶临界转速之上进行的实验表明,最佳的首次试重位置出现在不同的扇形区内,根据基本振动理论和实验结果可在这个区域内或附近选择合适的首次试重位置,提高动平衡精度。该研究结果有助于减少试重次数,提高动平衡效率。Based on a great deal of experimental data, the optimal position of first weighting in dynamic balancing of multi-bearing rotor was explored. The experiments under and up 1st critical speed show that, the optimal position of first weighting stays in a certain sector area. According to the basic vibration theory and experimental data, the position of the first test weights from that area could be selected to improve the precision of dynamic balancing. This result could help to decrease the times of start-up of machines and enhance the dynamic balancing efficiency.
