摘要
随着教育改革的不断深化,应用虚拟仿真技术开展实验教学,不仅能够辅助教师在课堂教学过程中讲解抽象晦涩的理论知识,而且能通过视觉感官激发学生的学习兴趣。文章针对“数值计算方法”课程中实用的数学工程化方法,依托南京理工大学的国防特色,建设“导弹制导打击”虚拟仿真实验。虚拟仿真实验通过设计目标运动建模、制导参数优化和任务弹道解算三个模块,将函数插值、最小二乘拟合和求解微分方程组等方法形象化地呈现在学生面前,通过调整不同参数或选择不同的解算方法得到的不同制导效果,帮助学生理解算法原理,启发学生思考。学校通过实践突破传统课堂授课的限制,为提高本科教学质量提供有力的保障。
With the deepening of educational reform,the application of virtual simulation technology in experimental teaching can not only help teachers explain abstract and obscure theoretical knowledge in the process of classroom teaching,but also stimulate students’interest in learning through visual senses.Aiming at the practical mathematical engineering method in the course of"Numerical Calculation Method",and relying on the national defense characteristics of Nanjing University of Technology,this paper constructs the virtual simulation experiment of"missile guided strike".By designing three modules of target motion modeling,guidance parameter optimization and mission trajectory solution,the virtual simulation experiment visually presents the methods of function interpolation,least square fitting and solving differential equations in front of students.By adjusting different parameters or selecting different solution methods,different guidance effects are obtained to help students understand the principle of the algorithm and inspire students to think.Through practice,the University breaks through the limitations of traditional classroom teaching and provides a strong guarantee for improving the quality of undergraduate teaching.
