%X 现代战争对诸如多管火箭、火炮、坦克、装甲车辆等常规武器的射击密集度的要求不断提高。射击密集度差、试验用弹量大、发射不安全成为制约现代常规武器发展的难题。武器射击密集度和发射安全性取决于武器系统动力学规律，发射动力学作为研究武器系统发射过程中受力和运动规律的一门新兴学科分支，在国际上已成为提高武器射击密集度和发射安全性的新技术突破口。针对上述情况，介绍了多体系统发射动力学理论与技术进展及其在武器射击密集度和安全性设计与试验中的应用，为武器射击密集度和安全性设计与试验提供新理论与技术。<br>The high firing precision has been continuously required by modern war for weapon systems such as multiple launch rocket system, artillery, tank and armored vehicle. However, bad firing precision, huge consumption of rockets in test and launch unsafety are hard technical problems restricting the development of these modern weapon systems. The firing precision and the launch safety depend on dynamics of the corresponding weapon system. As an engineering subject studying the motion and force for weapon system during launch process, launch dynamics has been a novel sally port to improve the firing precision and to ensure launch safety of weapon systems. In this paper, the theory and technology of launch dynamics of multi body system as well as its applications in the design and test of firing precision and safety for weapon systems are studied. It can provide new theory and technology for the design and test of firing precision and safety of weapons．
