| 1. | Damping was then determined via exciting the equation at the critical frequency to get the transit decay which was then analyzed with the moving - block method . in chapter 4 , the nonlinear dynamic equation of rotor - body system with inter - blade dampers ( taking all possible attachment offsets into consideration , spanwise offset , vertical offset and in - plane offset ) was modeled 本文重点推导了带叶间减摆器(减摆器带三个外伸量:展向,垂向和旋转方向)的旋翼/机体耦合系统的非线性动力学方程,针对该方程提出了一种改进的多桨叶坐标变换方法。 |
