摘　　要：针对无人机伞降回收系统设计,利用面向对象的开放式"降落伞回收系统仿真平台"实现了无人机伞降回收系统的十二自由度仿真,利用回收过程动力学仿真,拓展了无人机伞降回收系统设计方法。与回收系统工程设计方法相比,基于动力学仿真的设计方法能够考虑除最大许可着陆速度之外的开伞力峰值等其他设计指标,进一步细化降落伞设计参数选择。Based on the object-oriented opening framework of parachute recovery and landing simulation software system,this paper implemented a 12 DOF simulation model for UAV parachute recovery systems,extended the traditional parachute recovery system design methods with the dynamic simulation.This method makes it possible to consider more design criteria such as the peak values of the canopy opening load besides the maximal allowed landing velocity of the traditional design method.Detailed designs and parameters optimizations can be easily carry out with the method.
