摘　　要：针对航母蒸汽弹射器,在对其受力及热力学分析的基础上,建立其动力学模型,利用MATLAB软件建立了仿真系统进行数值计算,得到舰载机运动加速度、速度的大小及其与位移的关系,其计算方法是可行的;对多种弹射工况进行了仿真分析,获得不同工况下舰载机的弹射起飞运动特性,为弹射器的设计提供了可选方法及参数。Based on the analysis of loading and thermo-dynamics, the dynamic model is established for the steam-powered catapult in the environment of MATLAB software. It can simulate the accelerations and velocities of the carrier-borne aircrafts as well as the relationships of them with displacements. Various launch cases are simulated to find out the dynamic characteristics of the aircraft under different launching conditions. The numerical results provide the optional method and parameters for design of the catapults.
