反推装置操纵力动力学仿真与优化改进
Dynamic Simulation and Improvement Study of Thrust Reverser Control Force
摘要
Abstract
The failure of control force and torque of a grab-type thrust reverser affects the flexibility of the thrust reverser and the deceleration effect on aircraft landing.The modelling object is simplified by studying the transmission characteristics of the control mechanism,an efficient dynamic simulation 3D model of the thrust reverser control mechanism is established,and the motion simulation results are verified,which can meet the needs of component motion visualisation and control dynamics research.The variation curve and upper limit of the control force and torque,the influence of friction and the influence of pulley and tie rod debugging are stud-ied by simulation.The research results provide research ideas and evaluation bases for solving the above prob-lems,and improvement measures such as changing the index of the control force to the reference value of 25 N and lengthening the tie rod-003 to reduce the control torque are proposed.关键词
