摘　　要：快速直观地再现枪弹侵彻人体过程中伤道形成过程,为人体易损性评估提供准确的人体损伤数据。首先构建枪弹侵彻明胶靶标过程中的枪弹运动方程和明胶内瞬时空腔运动方程。接着使用C++语言,在OpenGL规范的基础上,对枪弹运动、空腔膨胀设计了可视化算法程序。程序可以通过数据实时驱动,实现枪弹运动和明胶空腔膨胀的动态变形仿真。将某7.62mm枪弹侵彻明胶的伤道可视化仿真与相应实验进行了对比,验证了仿真的准确性。上述程序可作为人体易损性评估软件的一个模块,用于快速直观地再现枪弹对人体的杀伤效应。This paper quickly and intuitively reproduces the formation process of the wound path in the process of the projectile penetrating the human body,and provides accurate human injury data for human vulnerability assessment.Firstly,the motion equations of the bullet and the temporarycavity in the gelatin were established.Then using the C++language,on the basis of OpenGL specification,the visual algorithm program was designed for the motion of bullet and cavity expansion.The program can be driven in real-time by data to simulate the bullet movement and the dynamic deformation of the expansion of the gelatin cavity.The visual simulation of a 7.62mm bulletpenetrating gelatin was compared with the corresponding experiment,and the simulation accuracy was verified.The program can be used as a module of human vulnerability assessment software to quickly and intuitively reproduce the terminal effects of a bullet on the human body.
