摘　　要：利用回归设计的方法,进行二次回归正交组合试验,建立颗粒阻尼减振特性的非线性回归模型。将该模型应用于预测,并通过试验验证该回归模型的正确性。最后通过分析得到颗粒阻尼减振特性与主要参数之间的变化规律,并利用非线性优化的方法对颗粒阻尼的参数进行优化设计。A guadratic regression orthogonal combination experiment was designed for the study of particle damping with the use of the regression design method. The non-linear regression model of the performance of particle damping was established by regression analysis. The model was used in forecasting. The validity and correctness of the model were tested and verified. At last, the relation between the performance of particle damping and some main parameters of the model was found. The non-linear optimization was used to determine these parameters of the model.
