In this paper the mathematical model of the kinematic char-acteristies and dynamic characteristics have been set up by ana-lyzing the pulldown film mechanism with cank swing block of the intermittent high speed cine-camera.According to this model a kind of the convenient and fast CAD softwares is proposed.It also indicates that the acceleration is the main factor determining the force of the pulldown mechanism.The optimal design for the basic elements of this mechanism has been realized by using a IBM PC/XT microcomputer.
