چکیده

In this study, dynamic behavior of safety mechanism of a mechanical controller is investigated using 3D-FE simulation. This paper is concentrated on controller of a high acceleration projectile. The controller is located in the top of the projectile. Safety mechanism is divided to deformable and rigid parts. Deformable and rigid parts are simulated in Abaqus and Adams commercial soft wares; respectively. The goal of this study is to investigate the safety mechanism operation includes plastic deformation of safety ring, rotor rotation and the required time for this operation. Also, some important parameters of safety mechanism such as, determination of required time and angular velocity for plastic deformation of safety ring, exit of safety pin, and the angular velocity correspondent to rotor rotation, when the axis of needle and guide hole are aligned, are studied.
