对两墨辊的对滚转动进行了模拟仿真分析，旨在研究相邻墨区之间的相互作用，以及主动辊的串动对油墨流动特性的影响。为此，以相邻5个墨区进行仿真分析。对中间墨区墨量等于、小于和大于相邻墨区3种情况下墨辊的对滚转动模拟仿真，以对比分析相邻墨区对中间墨区的影响。分析得出，在两墨辊对滚转动的过程中，相邻墨区之间相互作用，使得墨辊上油墨流场的压力、轴向速度、墨层厚度都受到影响。对主动辊有轴向串动时，分析中间墨区的压力、轴向速度、墨层厚度可知，主动辊的串动增大了相邻墨区之间的相互影响。

To analyze the interaction of adjacent ink areas and the effects of ink flow characteristics caused by the driving roller's axial movement, this paper simulates five adjacent ink areas on two rotating ink rollers. By simulating three conditions that the ink amount of the middle ink area is equal to, less than, and greater than that of the adjacent ink areas, the effect of the middle ink area caused by its adjacent ink areas on each side is analyzed. Analysis show that in the printing process, the pressure and speed and ink layer thickness of ink on the ink roller are affected by the interaction of adjacent ink areas. For the driving roller with an axial speed, by analyzing the ink pressure, the axial speed and the ink thickness of the middle ink area, it is found that the axial speed promotes the ink flow and enhances the interaction of adjacent ink areas.
