K9 자주포 설계의 인간공학적 평가 및 개선 사례 = Ergonomic Evaluation and Improvement Case of K9 Self-propelled Howitzer Design

다국어 초록 (Multilingual Abstract)

Objective: The present study aims to conduct an ergonomic evaluation of a revised design of the K9 self-propelled howitzer (SPH) through the application of digital human modeling and simulation techniques.
Background: As K9 SPH is exported to various countries, a revision of the K9 SPH design to better fit the anthropometric characteristics of operators and the concepts of weapon operation of the target export country is needed.
Method: Information was collected on the revised design of K9 SPH, representative anthropometric characteristics of operators of the target population, crew members and their tasks, and design requirements. Various ergonomic evaluations were conducted with the representative human models in the revised SPH while performing mission tasks using Technomatix Jack software.
Results: The evaluation results of the revised K9 SPH design were presented in terms of visibility, reach, posture, clearance, and accessibility. For the revised design that failed to meet the design requirements, issues and modified designs were informed to the design engineers.
Conclusion: The ergonomic evaluation of the present study demonstrates the usefulness of digital human modeling and simulation techniques in identifying design problems and proposes a modified design in the development of a revised product design.
Application: The findings from this research offer foundational knowledge to design, evaluate, and, when necessary, modify and improve a product.
