摘要
为了解决现有起落架安装设备存在的工作自由度较少及装置自动化程度不足等问题,基于3-PRS空间并联机构原理设计了一种新型起落架安装车。根据飞机起落架装配步骤的特点和人机工程学的设计原则,对某型飞机起落架安装车调姿装置进行轻量化设计;采用理论分析及有限元仿真的方法,以提高起落架安装效率、提高安装设备工作自由度为设计目标,确定了新型起落架安装车整体尺寸;通过仿真分析,确定了姿态调整装置的固有频率和振型,研究了外部激励对3-PRS空间并联机构与顶升立柱连接部位幅值频率曲线的影响,通过幅值频率曲线确定了调姿装置可能发生的共振频率。设计研究结果可为起落架安装车调姿装置的优化设计提供一定的理论参考。
In order to solve the existing undercarriage installation equipment work with less degree of freedom and device automation problems, a new type of landing gear installation car is designed based on the principle of 3-PRS spatial parallel mechanism. According to the design principles and characteristics of ergonomics in aircraft landing gear assembly steps, the lightweight design of aircraft undercarriage installation car position device is designed. Using the methods of theoretical analysis and finite element simulation, on the purpose of improving the undercarriage installation efficiency, and improving equipment installation work freedom, the new undercarriage installation car overall size is determined. Through the simulation analysis, the natural frequency and vibration mode of attitude adjustment device is determined, external excitation effect on 3-PRS space parallel mechanism and lifting column connecting parts of the amplitude frequency curve is research, the resonance frequency adjusting device be determined by the amplitude frequency curve of coal. The result can provide some theoretical reference for the optimization design of the landing gear installation vehicle attitude adjustment device.
