摘　要：根据弹丸冲击靶板的基本原理，采用ANSYSLS-DYNA 有限元分析软件，对漂浮式球形靶标就高速弹丸的冲击进行了仿真研究，得到了弹丸对靶标不同位置冲击时的加速度时程曲线及不同位置加速度的峰值。通过前期仿真计算减少了试验调试时间与难度，对设置漂浮式靶标内置加速度传感器初始触发值具有重要指导意义。

Abstract：According to the basic principle of projectile impact target，the impact of high-speed projectile on floating spherical target is simulated by ANSYSLS-DYNA finite element analysis software.The time history curve of acceleration and the peak value of acceleration at different positions are obtained when the projectile im⁃pacts the target at different positions.Preliminary simulation calculation reduces the test debugging time and diffi⁃culty，reduces the test cost，and has important guiding significance for setting the initial trigger value of the built-in acceleration sensor of floating target.
