摘　　要：运用IPRK法对典型弹药系统基础振动激励问题进行了研究．在阐述IPRK法基本原理的基础上，根据典型弹药系统包装形式构建了基于易损部件的三自由度弹药公路运输振动力学模型．结合实例对IPRK法和高斯白噪声模拟的有效性进行了验证，同时通过与传统Runge-Kutta法进行比较，验证了方法具有很高的计算精度和计算效率,最后运用IPRK法分析了包装箱质量、缓冲包装刚度和阻尼对引信振动加速度响应的影响规律．An effective algorithm based on improved precise Runge-Kutta integration （IPRK） is proposed for studying a vibration problem of typical ammunition system. The basic principle of IPRK method is introduced, and the three degree-of-freedom vibration model of ammunition based on vulnerable component under highway transportation was established by analyzing packaging form. Then the validity of IPRK method and Gaussian white noise was verified, and case study results show that the computation efficiency and accuracy of the method is higher compared with the conventional Runge-Kutta method. Finally, the influences of packaging case mass, cushioning packaging stiffness and damp on the vibration acceleration response of fuze were analyzed using IPRK method.
