全机结构试验起落架随动加载技术研究

摘要

以提高起落架试验加载精度为目的，提出了一种适用于全机状态下起落架试验的随动加载方法；并设计了随动加载装置，进行了试验验证及实际应用。与传统加载方式相比，随动加载装置具有加载精度高、结构简单、安装方便的特点，有较高的工程应用价值。%To improve the accuracy for the purpose of undercarriage loading , a self-adaptable loading method was presented for the undercarriage test based on full scale aircraft;the self-adaptable loading device was designed;and its performance was validated and utilized .The device is very important in engineering application with obvious advantages compared with the traditional one , including higher loading precision , conciser structure , and more con-venient installation .
