摘要
飞机副翼操纵系统动刚度试验是飞机飞行控制系统地面半物理模拟试验项目中新增的一项重要试验,是为了验证飞机在空中正常飞行时,副翼舵面在突然持续受到一定幅值、频率大小的正弦交变干扰载荷作用力后,飞行员是否还能正常操纵飞机飞行或降落,但计算飞机副翼操纵系统动刚度是此试验中的一项技术难点。经技术攻关,研究出利用飞机副翼操纵系统谐振峰值、谐振频率和静刚度的测量值来计算最小动刚度的方法,解决了飞机副翼操纵系统动刚度计算及测量的难题,同时该技术也可用于飞机升降舵、方向舵操纵系统最小动刚度的计算。
Dynamic stiffness test of aircraft aileron control system is an important new test in ground semi physical simulation test project for aircraft flight control system,aiming to verify whether pilots are able to control aircraft normally flying or landing,after aileron control surfaces are influenced suddenly and constantly by sinusoidal alternating load with a size of amplitude and frequency,when aircrafts normally fly in the air.Calculating dynamic stiffness of aileron control system is just a technical difficulty in the test.After tackling key technical problems,a mothed to calculate the minimum dynamic stiffness by using resonance peak,resonance frequency and measured static stiffness of the aileron control system is pre- sented,which solves the above problems.At the same time,the technology also can be used for calculating the minimum dynamic stiffness of aircraft elevator and rudder control system.
