摘　　要：为建立钨球破片速度预报模型,在通过理论分析得到破片速度衰减规律模型,根据Φ8 mm钨球破片在高速和中速段速度试验,进一步采用非线性分析的方法建立了破片高速和中速的速度衰减模型;由数据融合的方法建立了可预报破片某点处速度的经验公式。计算和试验结果验证了破片速度衰减模型和速度预报经验公式的正确性和实用性,拓展了球形破片速度预报公式的使用范围。To establish velocity prediction model of spherical fragment,firstly,through theory analysis,velocity attenuation regularity model of fragments was achieved; and then velocity attenuation model of high speed and medium speed was established by means of nonlinear analysis with the experiment of Φ8 mm spherical fragment at high speed and medium speed; Finally,empirical formula was established for forecasting fragment velocity of any point. Calculation results and experimental results proved the correctness and practicability of velocity attenuation model and empirical formula of speed forecast,and the range of speed forecast formula of spherical fragment was extended.
