Research on the Longitudinal Short-Cycle Mode Verification of Flight Simulator Based on Flight Parameters

对某型飞行模拟器纵向短周期模态的验证研究进行探讨。采用运动轨迹分析的方法,成功提取模拟器仿真数据短周期模态的模态参数。并通过Thile不等式系数法和窗谱估计分析的方法对飞行模拟仿真数据和飞参数据进行量化评估,验证仿真模拟数据和飞参数据阻尼比参数的一致性,验证该型飞行模拟器纵向短周期模态逼真度较好。

Discusses the verification research of the longitudinal short period mode of a flight simulator. The modal parameters of the simulator simulation data short-cycle mode are extracted successfully. And through the Thile inequality coefficient method and the analysis of window spectrum estimation method for flight simulation data and parameters according to the quantitative evaluation, to verify the simulation data and the consistency of the flying parameters according to the damping ratio shows that the longitudinal short-period mode type flight simulator has good quality.
