Study on Force Moment Characteristics of Rotating Disk Synchronization Shutter

Aim\ Introduces a indirect method to test the force moment characteristics of rotating disk synchronigation shutter of ballistic photography theodolite, this method can be used to test the armature voltage and current of the synchronigation shutter controlling system, respectively. Which is implemented paralleledly with the force moment self reangling machine hauled by the operated mechanism of DC seruomotor. Methods\ The force moment characteristics of rotating disk synchronigation shutter has been computed by applying the electric hauling theory. Results\ The force moment characteristics is the key to study its synchroniyation accuracy and shot frequency stability. Conclusion\ The fact shows that this method is feasible and valid.
