摘　　要：利用回归设计的方法对颗粒阻尼进行二次回归正交组合试验,建立了其减振特性的非线性回归模型,并通过试验验证了该回归模型的正确性。分析得到颗粒阻尼减振特性与主要参数之间的关系,并利用非线性优化的方法对颗粒阻尼的参数进行了优化设计。A quadric regression orthogonal combination experiment was designed for the study of particle damping by using the regression design method. And a non-linear regression model of the performance of particle damping was established by regression analysis. The model was used in forecast and the validity of it was tested and verified. At last, the regularity between the performance of particle damping and parametric variable was found by analysis. And the non-linear regression model was optimized as well.
