在实验研究间歇输片过程中胶片的微观运动规律时,发现输片力是不连续的,这与国内外有关输片力研究的报导不一致。本文根据间歇输片的实际情况,在近似假设的基础上,建立了新的间歇输片动力学模型,推导出输片力函数表达式,并用计算机模拟胶片在片道中的运动过程,图示了全输片力曲线,解释了实验结果,为输片力的精确研究打下了基础。 In the experimental study of the microcosmic motion of film during intermittent film transport, it was found that the film tension was discontinuous, which was inconsistent with the reports about the force transfer in the world. According to the actual situation of intermittent transport, a new intermittent transport dynamics model is established on the basis of approximate assumptions. The expression of the transfer force function is deduced and the motion of the film in the track is simulated by computer. All the film transfer force curve, explain the experimental results, lay the foundation for the accurate study of the film transfer force.
