摘　　要：为了开展大学物理课程的生动形象化教学、增强大学物理与工程技术的结合度,针对刚体力学中的进动进行了理论及应用拓展研究。由进动方程分析了车轮进动的具体运动特点,通过陀螺仪的实物演示揭示了飞机导航仪的工作原理,炮膛中的来复线表明了炮弹飞行中包含进动。工程应用实例的引出表明了大学物理知识点的具体应用,必然会提高教学效果与质量。In order to carry out vivid visualization of teaching and enhance the integration degree of physics and engineering, the precession in rigid body mechanics has been researched by means of theory and application development. The precession movement of the wheel characteristics can be analyzed by the precession equation. The working principle of the aircraft navigation can be revealed through physical demonstration of the gyroscope. The precession can be included in the flight of shell by the rifling of bore.The introductions of engineering application indicate the application of physical knowledge. As a result, teaching effectiveness and quality can be improved.
