Military vehicles are subject to variable extreme loads that consequently lead to fractures of chassis components. In the early design stage, it is important to evaluate their strengths and service load conditions not only for preventing these failures but also for reducing cost and weight. Thus, it is required to determine the allowable stresses of main parts under static load cases while no data on road load is available. This study now describes the analytic method applied to obtain the strength criterion of each subsystem using stress analysis and durability load history for a heavy-duty military truck. Selecting the maximum load history applied to the component through static durability analysis was thus necessary. A sine-wave dynamic stress history was constructed to reach the damage similar to the main load history. The allowable stress corresponding to a target life of each part was established using the optimization algorithm at MSC/Fatigue software. This process is very useful because the durability performances of chassis components can be investigated from static stress analysis based on the effective exciting load and comparison of allowable stress and maximum stress in the layout stage.
