飞机操纵面颤振是飞机颤振领域里最复杂的部分,在所发生的颤振事故中,操纵面颤振最为常见,但进行操纵面颤振分析,在模型简化、气功力计算等方面存在一定难度。本文结合某型飞机的研制过程,针对某型飞机在地面试验过程中出现主操纵舵面方向舵与其方向舵机械备份作动器舵面发生颤振现象,通过比较仿真结果和试验结果,提出几种解决方案,来抑制消除方向舵的耦合振荡。
The flutter of aircraft control surface is the most complex part in the field of aircraft flutter. Flutter of control surfaces is most common in flutter accidents, but flutter analysis of control surfaces has existed in model simplification and qq calculation A certain degree of difficulty. In this paper, a certain type of aircraft development process, for a type of aircraft in the ground test process appears main rudder rudder rudder rudder with its rudder mechanical backup actuator chatter phenomenon by comparing the simulation results and test results, put forward several solutions Program to suppress the elimination of the rudder coupling oscillation.
