Abstract

For wheeled self-propelled gun dynamics simulation, the study did not consider of the flexibility of the suspension system currently. And wheeled self-propelled gun with complex road and huge fire load, suspension arm are more likely to happen elastic deformation and fatigue damage compared with civil car. In order to improve the model accuracy and explore the stress-strain law, established a rigid-flexible coupling wheeled self-propelled gun vehicle model based on multi-body dynamics, finite element method, and artillery launch dynamics theory. By analyzing the driving and firing model with different conditions, finally to obtain the position of the suspension system prone to damage, easy to have the damage condition and the maximum stress and strain results. Studies have shown that wheeled self-propelled gun dynamic model establishment of flexible suspension is necessary. The analysis results of self-propelled guns suspension system damage mechanism analysis, the fatigue strength analysis has certain reference value.
