摘要
对70 mm间歇式同步高速摄影机的曲柄摇杆式抓片机构动平衡计算方法、实施途径和结果进行了分析研究.利用MSC/Visual Nastran Desktop软件,在该抓片机构虚拟样机上进行了动平衡计算.计算结果为工程设计提供了可靠的设计数据和理论依据,改善了实际的动平衡质量,提高了摄影频率.应用实践证明,采用动力学仿真方法进行动平衡计算,可简化抓片机构动平衡的计算过程,并提高了计算准确度和设计效率.
The 70 mm high speed photographic camera （HSPC） and its film-transport mechanism were introduced. The method for calculate the dynamics balance of crank-rocker film pull-down mechanisms was described. The result was analyzed too. Result of dynamics simulation provided credible data is used for engineering design. The optimial dynamic balance is able to improve photo frequency. This way is more simple, exact and practical.
