Paper Title:
Analysis of Dynamic Behavior of Zigzag Groove Setback Arming Device with Two Degree of Freedom
  Abstract

Focusing on the requirements of safety and reliability of fuze setback arming device of rocket-assisted projectile, a zigzag groove setback device with two degree of freedom was designed with Inventor 6. The dynamic simulation is developed under environment of VisualNastran. The optimum parameters of up inertia-cylinder mass, down inertia-cylinder mass, up inertia-spring rigidity and down inertia-spring rigidity were tested by orthogonal method and simulated. The results indicate that this setback device can effectively differentiate setback overload in launch and impact overload at service handling; credible arming time of fuze is about 128ms when the even overload of the rocket engine is 100g; the optimum mass of up inertia-cylinder and down inertia-cylinder are respectively 3.19g and 1.41g, the optimum rigidity of up inertia-spring and down inertia-spring are respectively 32.7 N/m and 21.8 N/m.
