| 摘要: |
| 文章研究了多刚体系统动力学理论应用于折叠机翼变体飞机动力学建模的方法,考虑变体飞机为一个完整的多刚体系统,建立了能够完整描述变形过程的动力学模型。针对对称变形和非对称变形进行了变体飞机的动态变量特性分析,并基于MATLAB-Simulink仿真环境,建立了非线性数值仿真模型。以某型折叠机翼变体飞机为算例进行了仿真,结果表明建模方法正确可行。 |

| Abstract: |
| We present a new method of dynamic modeling.Sections 1 through 4 of the full paper explain our mod-eling and analysis mentioned in the title, which we believe is effective and whose core consists of: "Taking thefolding wing morphing aircraft as a full multi-rigid-body system, we derive the dynamic equations that can depictthe full morphing process.The characteristics of dynamic variables for both symmetry and asymmetry morphing areresearched.Based on this modeling, we build the nonlinear numerical simulation model utilizing the Simulink mod-ule in the MATLAB software and then do the simulation for a folding wing morphing aircraft".The simulation re-sults, presented in Figs.5 and 6, and their analysis show preliminarily the correctness and effectiveness of our newmethod of modeling. |
