| 摘 要： | 长焦距、大画幅、高分辨力胶片摄影相机要求在给定的摄影周期内快速、精密地将胶片展平在片台上.为了在设计中准确、高效地确定胶片负压展平系统的片台结构参数、真空泵参数及电磁阀参数等,本文给出了一种用数值计算对胶片负压展平过程进行计算机模拟的方法.经实践证明本方法是行之有效的.

| Abstract: | In a long focus, large frame and high resolution film camera, its film is demanded to be flatted quickly and precisely on a film flatness plate within a given time in taking a photograph. To accurately and availably ascertain the structure parameters of the film flatness plate, vacuum pump parameters and electromagnetic valve parameters in the film flattening system, the paper describes a numerical modeling method of a film flattening process, which has been practically demonstrated to be effective. |
