Buffer and Vibration Optimization of Missile Data Recorder Structure

Abstract:

On the analysis of the original data recorder, made several key problems clear when buffer and damping, distinguished between a cushion theory and application field of stress wave theory, the traditional rigid spring-buffer model whose object is to reduce the impact of acceleration that can not accurately describe the elastic force of the part of the actual situation; the stress wave theory is the elastic theory can explain the filter buffer question from the micro-small space, from this designed a composite structure for vibration reduction, which made the dynamic stress of protected component down about one order of magnitude. Optimization with Isight and Ls-dyna, the protected component's dynamic stress down about 69.3% and the data recorder's quality 300g lower, finally passed the Marshall Hammer test successfully.
