The realization of high response hydraulic Wing Tip Brake (WTB) is a complex problem integrating technologies such as fluid,friction,electromagnetic and heat dissipation technology.This paper presents a method for the research and development of high response hydraulic WTB for a large aircraft High Lift System (HLS).Firstly,we use the Simulink virtual simulation to calculate the response time of the WTB,and the simulation results show that the main factors affecting the response time include environmental temperature and fluid throttling,etc.Secondly,according to the high response requirement of a large aircraft high lift system under asymmetric fault,we propose to add the throttle valve in the WTB hydraulic system to raise the product internal temperature,and use the ANSYS thermal simulation to analyze the WTB internal warming at low temperature.Finally,the results of simulation analysis are verified by experiments.The experimental results show that the response time analysis based on the model and the thermal analysis model coincide with the actual results,and meet the need of HLS on high response for hydraulic WTB.%针对高响应液压翼尖制动装置的实现是集流体、摩擦、电磁和散热等技术的复杂问题,提出一种大型客机高升力系统高响应液压翼尖制动装置研究和实现的方法.首先,利用Simulink虚拟仿真对该液压翼尖制动装置的响应时间进行分析,通过仿真分析发现影响响应时间的主要因素包括环境温度和阀口节流等;其次,根据某大型客机高升力系统不对称故障时的高响应需求,提出了给产品液压系统增加节流阀来提升产品内部温度的技术方案,并利用ANSYS热分析对该方案在低温条件下的温升进行仿真计算;最后,通过试验验证仿真分析结果.试验结果表明,基于模型的响应时间分析和热分析模型与实际结果吻合,实现了高升力系统对液压翼尖制动装置高响应的需求.
