针对CTP成像滚筒平衡状态多变的特点，根据刚性转子动平衡原理，完成了动平衡机对成像滚筒的配重实验。基于实验，找出了滚筒旋转过程中不平衡的机理和机构平衡块移动及定位的基本规律，为解决印版幅面尺寸变化而产生的滚筒不平衡提供了实验依据。此配重实验在测试、产品组装及设备使用过程中的调节等方面，还存在精度不高、效率低等问题。

Counterweight experiment of the dynamic balancing mechanisms of imaging roller was carried out according to rigid rotor dynamic balance principle for the varied characteristics of balance status of the roller. The imbalance principle and the basic rule of mechanism balance block’s movement and positioning in the drum rotation process was found based on the experiments. The purpose was to provide an experimental basis to resolve the roller imbalance resulting from the various plate sizes. The minor deficiency is that this counterweight experiment has some problems on testing, product assembling and equipment adjusting during working process, such as low precision and low efficiency.
