| ABSTRACT |
|
The endurance tests of Korean military vehicles are conducted based on the total mileage and distance ratios for each test course presented in the U.S. Army’s TOP. However, the 2014 revision of the TOP recommends combining test courses in accordance with the OMS/MP of the weapon system. Therefore, research in an endurance test mode based on the army operational environment is essential. In this paper, we develop an integrated endurance test mode that optimally combines test courses by considering all major systems using military light tactical vehicle. To achieve this, the load factors that can represent chassis and powertrain system of LTV are selected and measured. The optimization factors for combining test courses are identified through frequency, relative damage and correlation analysis, and the target load is constructed to reflect army operational environment based on army annual training plan. Finally, NSGA-II, a multi-objective optimization suitable for creating integrated endurance test mode is employed and the final optimal solution is derived using comparison criteria. Additionally, the validity of this approach is confirmed through comparison of damage ratio and comparison with TOP mode. |
