| 摘 要： | 目前国内在处理起落架两数据中，大多采用应变值单向敏感的矩阵法处理，存在一定的局限性。 K8前起落架两数据处理中，在分析了力学与数理方法的基础上，采用数理统计中线性回归的方法进行处理，其数学模型为多元线性回归方程。采用的计算方法为逐步回归计算法。从计算结果分析，各方向载荷与理论情况比较接近，变化规律与真实情况相符合。

| Abstract: | The single side sensitive value matrix processing now used frequently in dealing with the two data of landing gear at home has a certain limitation .The linear regression of mathematical statistics is used to deal with the two data of landing gear of K8 aircraft after the dynamics and mathematics are analyzed.The mathematical model of this method is multivariable linear regression equation.The calculation method is stepwise regression.The variable rule of this method is coordinated with real condition.The loads on each direction approach to the theoretical condition and the varoabie rule according to the analyses of calculation results. |
