| 摘 要： | 为了研究飞机起落架受冲击载荷时的功量吸收状况，须在起落架落震试验中，对飞机着陆瞬间起落架机轮在空间三个方向上冲击位移的动态变化量进行测量。为此，本文设计了四自由度空间定位装置，并使其与计算机连接，实现了落震试验过程中，起落架在高速冲击状态下机轮三向位移的有效测量与记录。

| Abstract: | In order to study the absorbing work of undercarriage under the impact load in the landing gear drop test,it is necessary to measure the dynamic values of three direction displacement of aircraft wheel in the twinkling of the aircraft landing.Therefore,a space positional device with four degrees of freedom is designed and connected with the computer measurement system.By using this experiment device,the three direction displacement of aircraft wheel under the high speed impact load can be measured and recorded effectively. |
