Abstract

In view of issues such as great air damping influence and vertical clamping inconvenience on inertia moment measurement of large complex projectiles with wings or rudder, a measurement method of vibration pendulum was proposed.Projectile was horizontally clamped with the compound pendulum mechanism composed of knife-edge support and spring.At the same time, air damping wasreduced by making the swing axis away from its own axis line.The measurement theory and errors of the method were analyzed and the standard sample was measured.The results show that air damping effect on the process of measuring inertia moment of the projectiles with large size and complicated shape is reduced with the method.

Key words： large complex structure; cutting edge support; vibration pendulum mechanism; horizontal clamped; measurement errors; air damping
