摘要

摘要: 随着对导弹速度和精度等性能要求的提高,弹性特性已成为导弹动力学分析与设计中不可忽略的因素。弹性振动将对导弹的飞行特性和控制精度产生较大的影响。因此,在对弹性体导弹进行半物理仿真时,考虑弹体弹性振动所产生的影响,有利于提高仿真的真实度。本文发展了考虑弹体弹性的导弹飞行动力学数学仿真框架,建立了弹性体导弹半物理仿真系统各环节的数学模型,实现了半物理环节动力学模型在数学仿真框架中的集成与一体化仿真,并在此基础上分析了弹性振动和仿真设备在弹性体导弹半物理仿真中的影响,数值仿真结果表明,研究结果可以为考虑弹体弹性的导弹半物理仿真提供一定的理论基础。

Abstract: With the increasing requirements of velocity and accuracy, the elasticity has been a non-ignorable factor in the dynamic analysis and design of missiles, which could evidently influence the flight performance and control accuracy. In this case, considering the elastic vibration of missiles would improve the precision while running a hardware-in-the-loop simulation of a flexible missile. A flight dynamic model considering the elasticity was developed, and the model of hardware-in-the-loop simulation system was established at the same time. The integrated simulation of math simulation model and hardware-in-the-loop simulation model was realized, based on which, the influences of the elastic vibration and the simulation equipment were analyzed. The results could provide a theoretical basis for the future hardware-in-the-loop simulation of missiles considering the elasticity.
