摘要
针对具有非线性影响的飞机操纵面旋转模态测试,提出了基于伺服弹性地面试验的操纵面旋转模态测试方法,并以一真实飞机为对象进行了应用验证。试验结果表明,该方法是合理可行的,具有一定的工程应用价值。
Aiming at the rotation modes of control surface measure with nonlinear influence,a testing method of control surface rotation modes based on ground test of servo-elasticity is introduced in this paper.The method is validated by the aircraft test.The result is reasonable and feasible.This technology has a certain engineering application value for hypersonic vehicles.
