弹道摄影经纬仪同步快门拍摄频率稳定性研究

Study on force Moment Characteristics of Rotating DiskSynchronization Shutter of Ballistic Photography Theodolite

本文对弹道摄影经纬仪新型旋转盘片式同步快门的拍摄频率稳定性进行了专门的研究 ,并对其进行了全面细致的测试 ,然后对测试结果进行了详细的理论分析。研究中取得的结果是令人满意的 ,实验测试与理论分析相吻合。

This papr introduces an indirect method to test the force momnt characteristics of rotating disk synchronization shutter of ballistic photography theodolite,This method respectively test the armature voltage and current of the synchronization shutter controlling system, which is implemented paralleledly with the force moment self-reangling machine hauled by the operated mechanism of D C Servomotor. The force moment characteristics is the key and premise to study its synchronization accuracy and shot frequency stability.The fact shows that this method is feasible and valid.
