摘 要: 定量间歇输片系统是空间相机的重要组成部分之一,此系统要求完成供片、输片、收片任务,工作期间可依据需要进行单张或连续数张输片摄影。文中主要介绍了采用定量输片和带有张力控制的输片系统的设计,从定量输片机构的供、收片量片辊的运动特性出发,分析片带的运动特性,研究了输片力的变化规律,以此为依据进行张力感测与张力控制机构的设计,同时阐述了在设计中采取的一系列防止划片的技术措施。最后的实验结果表明,该设计满足空间相机对传输胶片的使用及精度要求。 As one of space camera's important subsystem, Fixed quantity intermittent film-transport system had to fufilled supplying film, transporting several film continuously to phtography. This paper mainly discussed the design of definite length intermittent film-transport system with tension-control machine. Conducting dynamic property of fixed quantity measuring film roller deduced the film's dynamic property and film tension. Based on film-tension analyses, the machine of film tension to be measured and controlled during the whole course was designed. And also expatiating the idea of preventing scratching film in this paper. Finally, the experiment of film-transport machine proved it correctly and this machine satisfied space camera's technology standard.
