Abstract

Abstract

Aiming at the high-g launching overload of the guided ammunition, the semi-strapdown stabilization platform in the shell is easily damaged when only the bearing bears axial high overload, the " counter-top hemisphere” structure was designed. Based on the analysis of the working principle and anti-overload design requirements of the semi-strapdown stabilization platform, this study analyzed the forces situation of " counter-top hemisphere” structure, the materials used were selected, and the finite element simulation analysis was performed. Finally, the structure was manufactured, and it was verified by semi-physical test. It was shown that when the semi-strapdown stabilization platform is subjected to high overload, the structure can play an effective protective role, when projectile and the internal semi-strapdown stabilization platform is under high overload condition, and provides the foundation forattitude measurement of theprojectile. The anti-high-overload buffer structure supports a stable and reliable working environment for the inertial measurement system, which has engineering application value. The inertial measurement system can still work stably and reliably when overload reaches 11 000g. The design has engineering application value.
