The equivalent linearization results obtained by probabilistic method are inducted to treat landing gear non linear parameters such as shock absorber air spring force, hydraulic damping and Coulomb friction, tire stiffness and damping.

• 引入了概率平均意义上的当量线性化方法 ,用该方法处理了起落架缓冲器空气弹簧、油液阻尼和库仑摩擦力以及轮胎刚度和阻尼等非线性参数。
