以印刷质量为出发点，分析和总结了印刷机械系统的典型工作环境和影响工作平稳性的各种因素。基于广义质量定义，提出了一种对平稳性各影响因素的影响程度的评价方法。以J2108型胶印机为例，研究结果表明：滚动振动引起的不平稳是影响印刷机工作平稳性的关键因素，传动不平衡和机件自身运动分别为主要和较主要的因素。研究为实际生产印刷质量和印刷机工作平稳性的控制提供参考。

The working environment and influencing factors for working stability of typical press mechanical system was analyzed and summarized based on printing quality. The evaluation method of influence degree of factors for working stability was put forward based on broad sense definition of quality. Model J2108 offset printer was studied as sample. The results showed that roller vibration is the key factor for working stability; transmission un-stability and work part movement are the main and secondary factor. The purpose was to provide references to control printing quality and working stability control of printer in actual production.
