摘　　要：对于两栖火炮来说,作战时能够实现水上快速浮渡,基于不同的海况条件可实现安全可靠的水上射击,是登陆作战能否成功的一项关键因素。为了掌握不同海况条件下两栖火炮发射安全性与稳定性,建立了两栖火炮水上发射动力学模型,获取了两栖火炮水上射击横摇角位移,结合两栖火炮水上射击横摇角测试,验证了动力学模型的计算精度。基于皮尔逊和莫斯克维奇海浪谱海面模型,建立了1~4级海况条件下两栖火炮横摇仿真模型,获取了两栖火炮不同海况条件下的横摇最大幅值及横摇周期,结合耐波性分析,为两栖火炮不同海况条件下的发射安全性进行了评估。For amphibious artillery,it is a key factor for the success of landing operations to realize rapid swimming and the safe and reliable firing in the water in different sea conditions.In order to know the firing safety and stability of amphibious artillery weapons under different sea conditions,a dynamic model of amphibious artillery weapon firing in the water was established,and the roll angle displacement of the weapon shooting in the water was obtained.With consideration of the roll angle test of amphibious artillery weapon shooting in the water,the calculation accuracy of the dynamic model was verified.Based on the Pierson and Moscowitz wave spectrum model of the sea surface,an amphibious artillery rolling simulation model was established under the conditions of seas conditions 1 to 4,the maximum amplitudes and rolling periods of the rolling amphibious artillery weapon under different sea conditions were obtained.Together with a seakeeping analysis,firing safety of amphibious artillery weapons was evaluated under different sea conditions.
