| Abstract: | The structure and principle of three-line pendulum are outlined. The calculation methods of its shimmy period in small and large angle are presented. The three-line pendulum can measure the rotational inertia of small missiles, missile wavheads, shells, aeroplane model and other stractural members. When RL<130 and φ 0≤60°, the measurement accuracy can be better than 1%. |
| Keywords: | shoulder-lanched missile three-line pendulum rotational inertia shimnny period measurement. |
