摘要
以某无人机撞网回收系统为例,基于LS-DYNA软件,提出了柔性带、阻尼器等关键部件的建模方法,建立了系统有限元仿真模型,进行了不同入网位置的动力学仿真计算,并用试验验证了仿真模型的准确性.仿真和试验结果表明:本文建立的无人机撞网回收系统模型具有较好的工程适用性,提出的动力学建模仿真方法具有一定的通用性.
For the direct dynamic simulation of unmanned aerial vehicle （UAV） net-recovery system, the modeling methods of key components such as flexible belt and damper were discussed. The finite element model of UAV net-recovery system was developed based on LS-DYNA, and the system dynamic simulations in several different impact locations were conducted. The finite element model was valid judging from the experiment results. The simulation and experiment results have shown that this system has a good engineering adaptability and the modeling methods are universal to certain extent.
