【摘要】 在工程实践中，弹簧的弹性力可认为只与该元件的变形有关，阻尼元件的阻尼力只与该阻尼元件的相对速度有关。文中内容正是从此点出发，结合随机振动理论，对统计线性化方法进行了简化，使之更有利于工程应用。应用此方法，对非线性振动方程中的参数进行了优化，得到了满意的结果更多还原

【Abstract】 In mechanic vibration system, the elastic forces can be considered only connected with the deformations of elastic elements and the damping force only has the relation with the velocity of damping elements. Considered all of above, with the theory of random vibrations, the paper simplified the method of Stat linearization. This can made it be used easily in projects. With this method, the paper made a parameters optimization in non linear random vibration system.更多还原
