Whenanamphibiousself-propelledgunlateralfiringonwater,itwouldresultingina substantial sway that will produce a serious threat to its stability. Taking an amphibious self-propelled gun lateral firing stability as the research object, a self-propelled gun amphibious rigid-flexible-coupled model has been created in the ADAMS/View. Based on multi-body model of topological structure building and launching load modeling, its rigid-flexible-coupled model of Launch dynamics for lateral firing on water has been completed. Through analysis of the computer simulation results, the paper reached the conclusion that small angles should be avoided in the lateral firing on water, in order to improve the stability of firing.%两栖自行火炮在进行水上横向射击时，产生的大幅度摇荡会对其稳定性产生严重的威胁。以某两栖自行火炮水上横向射击稳定性为研究对象，在ADAMS/View中建立某两栖自行火炮的刚柔耦合多体模型；通过对多体模型拓扑关系的构建与发射载荷的建模，完成其水上横向发射动力学模型；通过对该模型横向射击仿真结果的分析，得出在横向射击时应尽量避免小射角以提高射击稳定性的结论。
