2) landing gear test
起落架试验
1.
In the airplane landing gear test,the sport of the landing gear is spatial,the dynamic state space track needs to be meas- ured,of which is the axle center and the point of intersection of shake arm and the pillar.
飞机起落架试验中,起落架的运动是空间的,起落架轮轴中心、摇臂与支柱交点的动态空间轨迹需要测定,介绍了一种利用线位移传感器布置初始参数坐标并跟踪测量测试点空间坐标的方法,试验结果说明此方法简捷、实用。
3) Drop test
落震试验
1.
FEM software,ABAQUS,is used to model the landing gear for an aircraft,and carry out the numerical simulation for drop test.
利用大型商用有限元软件ABAQUS对某机起落架建模,并进行落震试验数值模拟。
2.
The model is verified by the drop tests of fixed orifice landing gear.
利用定油孔起落架的落震试验对该模型进行了校验。
3.
The mathematic model of predicting the horizontal load subjected to aeroplane undercarriage tyre based on the drop tests was built by analyzing dynamic loads acting on drop test platform which is supported by three poles, and the coefficients in the mathematic model were determined by means of the least square method according to the results of static tests.
通过分析 3点支撑落震平台的动态受力情况 ,确定了起落架机轮投放到落震平台上后 ,落震平台水平方向的各种载荷情况 ,从而利用测量落震平台水平载荷的间接测量方法 ,建立了起落架机轮水平载荷测量方法的数学模型 ,并采用在落震试验台水平方向上进行试验标定的方法 ,确定了数学模型中的有关待定系数 。
