항공 소재 물성 데이터에 대한 분포 적합성 비교 평가 및 고찰

Abstract

The aim of this study is to evaluate and select the most appropriate test methods for assessing the goodness of fit of aerospace material property data. Obtaining airworthiness certification is critical for ensuring aircraft operational use, and statistical analysis is crucial for verifying material properties through testing. The specimens selected to represent the material population must account for the diversity arising from production processes and exhibit the inherent variability, which may affect the material behavior. By employing these specimens, standardized tests are conducted, followed by statistical analyses to determine the material allowables. These allowables are integral to aircraft design because they significantly affect both performance and quality. Consequently, selecting the correct distribution for data analysis is crucial as it improves the modeling of material allowables and thus the overall reliability. Furthermore, this study can benefit the aerospace industry by offering comprehensive insights into material development, which can enhance quality and foster deeper understanding regarding material property data.
