摘　　要：针对军用桥梁的特点，分析了影响军用桥梁动态性能的主要因素，探讨了军用履带车辆一桥梁相互作用模型的建立，指出了在军用桥梁研制过程中采用虚拟样机技术的可行性与重要性，并给出了军用桥梁设计过程中冲击系数的合理确定方式。结合某型军用桥梁的动态试验结果，分析了影响冲击系数的主要因素。Aiming at the characteristics of military bridge, tne main formance of military bridge are analyzed. The progress to establish the interactive model of the tracked vehicle and military bridge is discussed, and the feasibility and importance of adopting virtual prototype technology during the manufacture of military bridge are presented. The reasonable way to determine the impact coefficient in the design of military bridge is proposed. Combined with the dynamic test results of a certain military bridge, the main factors that affect the impact coefficient are analyzed.
