Helikopter Transmisyon Bütünleme Tezgahının Dijital İnsan Modelleme Kullanılarak Ergonomik Değerlendirmesi ve Yeniden Tasarımı

Bu çalışmada, helikopter transmisyonunun montajında kullanılacak bir montaj fikstürü tasarlanmış ve Dijital İnsan Modelleme (DHM) yöntemleri kullanılarak ergonomik koşullara uygunluğu analiz edilmiştir. Analizlerde Hızlı Üst Ekstremite Değerlendirmesi (RULA) ve Biyomekanik Hareket Analizleri (BMA) kullanılmıştır. İnsanın ergonomik yeterliliği, iki farklı montaj koşulu için deneysel olarak analiz edilmiştir. Yeniden tasarlanan montaj fikstürü, geleneksel olanlara göre önemli ergonomik avantajlara sahiptir. Analizlere göre L4-L5 lomber vertebra disklerinde oluşan kompresyon yüklemesinde % 79,6, moment yüklemesinde % 94,3 avantaj sağlanmıştır. Sonuç olarak, işçilerin daha rahat ve güvenli bir şekilde çalışması için tasarlanan ergonomik montaj armatürünün amacına uygun olduğu ortaya çıkmıştır.

Ergonomics Assessment and Redesign of Helicopter Transmission Assembly Fixture Using Digital Human Models

Digital Human Modeling (DHM) is an integral part of computerized engineering studies. In this study, an assembly fixture has been designed that will be used in the assembly of the helicopter transmission and it has been analyzed for compliance of ergonomic conditions using DHM technique. Rapid Upper Limb Assessment (RULA) and Biomechanical Motion Analyses (BMA) were used in the analyses. The ergonomic competence of the human was analyzed empirically for two different assembly conditions. The assembly fixture redesigned has significant ergonomic advantages over the conventional ones. According to the analyses was provided that 79.6 % advantage in compression loading and 94.3 % advantage in moment loading, which occurs on the L4-L5 lumbar vertebra discs. As a result, it was revealed that the ergonomic assembly fixture designed for workers to work in a more comfortable and safe manner was suitable for its purpose.
