摘　　要：对摄影机的主要系统组成、工作原理和性能指标进行了简要介绍.论述了作为摄影机核心部件的曲柄摇杆式输片机构的类型、设计和动力学分析.为了适应两种不同的画幅尺寸要求(四片孔画幅尺寸为50×18.8mm,八片孔为50×36mm),设计并研制了两套输片机构.它们的接口形式和结构完全相同,可以方便用户快速更换,达到一机多用的目的.在该摄影机的研制过程中探索性地应用了虚拟制造技术,解决了由摄影频率提高而引起的一系列技术难题.虚拟制造的应用不仅提高了设计制造水平,同时也缩短了研制周期,降低了研制成本.实际应用证明了70mm间歇式高速摄影机的研制是成功的.The main buildup, working principle, performance and feature of the camera are introduced. As the key component, the film transport mechanism is described. To adapt two different size of pictures （four perforations for 50 × 18.8 mm, eight perforations for 50 ×36 mm）, two sets of film transport mechanisms are designed. They have the same structure and interface, which make it possible that the user can replace them quickly and expediently. Virtual Manufacturing （VM） technology is applied during the development of 70 mm HSPC to resolve a series of technical difficulties caused by increasing photograph frequency of HSPC. Actual use shows that development of 70 mm HSPC is successful.
