Abstract

Optical archival systems are subjected to many different types of shock environments. In particular, during transport, extremely large impacts and amplified shock accelerations are transmitted to the cartridge and container, leading to mechanical failure of the optical components. A polyoxymethylene container, equipped with two types of isolation structures (a beading structure and inner ribs), was developed for shock isolation. In this paper, explicit finite element analysis was performed to improve the shock container. The analysis results were verified with a linear drop test. Based on the verified numerical model, the shape of the shock isolators in the cartridge container was modified via the design of experiments methodology to accommodate the maximum stress. The shock isolation performance of the modified shock container of the modified isolators was improved by 32.8 %.
