民机飞机液压刹车系统动态特性参数灵敏度分析方法
Sensitivity analysis method for dynamic characteristics parameters of hydraulic braking system in civil aircraft
摘要
Abstract
A thorough theoretical and experimental investigation of the dynamic properties of the aircraft hydraulic braking system was carried out in order to improve the braking performance and dependability of civil aircraft under challenging runway circumstances.A detailed nonlinear mathematical model of the hydraulic braking system was established,incorporating key components such as the brake control valve and hydraulic pipelines.Based on this model,a parameter sensitivity analysis method was introduced to address the system's multi-parameter problem.The analysis quantitatively determined that the most important factors affecting the dynamic response characteristics of the system were the actuator piston's effective area,the actuator return spring's stiffness,and the flow-pressure coefficient of the valve.Finally,a hardware-in-the-loop experimental platform for the aircraft braking system was constructed to carry out experimental validation of the dynamic response.The results clarified the key factors affecting the braking system's dynamic response,confirmed the correctness of the theoretical analysis,and provided a clear direction for the design and optimization of hydraulic braking systems for civil aircraft.关键词
