摘　　要：抛投器广泛应用于多种救援场合,目前抛投器的动力主要有气动式和火药式两种。论文首次提出电磁抛投器的概念,介绍了电磁抛投器的基本结构和工作原理。由于电磁抛投器的次级抛体带有绳索,考虑绳索对抛体空间运动的影响,本文建立了抛体射出后空间运动的状态方程,对不同出射角度的抛体空间运动过程进行仿真,分析了绳索对次级抛体空间运动的影响规律。Throwing device is widely used in many rescue occasions, and its powei＂ manly comes from pneumatic and powder at present. This paper firstly puts forward the concept of electromagnetic throwing device, and introduces its basic structure and work principle. Because electromagnetic throwing device＇s secondary projectile has a rope, considering its impact to the projectile＇s movement in space, this paper establishes a stateequation for projectile＇s movement in space after it is emitted out, simulates the projectile＇s motion process in space with different emission angle, and analyzes the influence regularity that the rope impacts on secondary projectile＇s motion in .~nae~
