| 摘 要： | 在舰艇抗冲击试验中，爆距直接影响到对目标的毁伤效果，爆距的误差范围也直接影响到试验数据的处理，因此，依据爆距的要求，需要对爆源布放沉底后进行准确的定位. 准确计算出爆源布放至海底的位置尤为重要. 本文对试验中爆源布放后布放索及浮漂在水中的受力情况进行了分析，建立了爆源布放索-浮漂系统受力的数学模型，采用Runge-Kutta 方法和Newton 迭代法计算出浮漂的漂移量，并给出了具体的算例.

| Abstract: | It is very important to locate the explosion source in the impact test. In this paper, a dynamic model of the buoy-cable system is established based on the force on cylinders in the uniform water flows. With the new model, the location of the buoy is dermined by using a numerical method based on the Runge-Kutta method and the Newton iteration. |
