间歇式高速摄影机全输片力研究

Perfectly Studying the Force of the Film-Transport of the Intermittent High Speed Camera

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。

During experimentally investigating the micro-motion law ofthe film in the process of the intermittent film-transport,we find a result,di-fferent from those given by domestic and abroad researchers,that the force ofthe film-transport is not continuous.In this paper,we set up a new dynamicmodel of the intermittent film-transport on the bases of the practical film-transport and the approximate assumptions,from which we derived the expressionof the force of the film-transport,simulated the moving process of the film inthe film road on computer,showed out the curves of the force of the film-transport and finally gave out the explanations to the experimental results.
