| 摘 要： | 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.根据起落架落震试验结果和该数学模型,可以得到考虑动态效应的起落架机轮水平载荷.应用结果表明,提出的测量起落架机轮水平载荷的方法比原来使用的静力测量方法更合理、更可信.

| Abstract: | 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. Then the horizontal load to aeroplane undercarriage tyre can be obtained more accurately by making use of the proposed model and results of drop test simultaneously. The practical uses of the proposed method shows that it is more reasonable and more reliable than the method used in former Russia. |
