Abstract

In this paper, we have obtained the acceleration coefficient of the IMU (Inertial Measurement Unit) to prove reliability by analyzing the characteristic of the MEMS IMU installed in guided weapon systems for overseas export and the operating environment of the guided weapon system. Additionally, based on designed life testing, we performed life tests on three the IMUs and demonstrated a target lifetime of 12 years.

본 논문에서는 해외수출용 유도무기체계에 탑재되는 MEMS 관성측정기의 특성과 탑재되는 유도무기체계의 운용 환경 분석을 통해서 신뢰성 입증을 위한 관성측정기 가속계수를 도출하고, 이를 기반으로 관성측정기 수명 시험을 설계하였다. 또한 설계된 수명 시험을 토대로 관성측정기 3조에 대한 수명 시험 수행을 통해 12년의 목표 수명을 입증하였다.
