重圆盘在粗糙平面上滚动时的摄动解

Singularly Perturbed Solution of a Heavy Circular Plate Roll on the Asperity Plane Surface

本文应用多重尺度法研究重圆盘在粗糙平面上滚动时得到二阶非线性微分方程组，并构造出解的渐近展开式。

In this paper, we consider the roll of heavy circular plate on the asperityplane surface with second-order nonlinear differential equations By using the methods of multiple scales, the asymptotic expansion of solution isconstructed.
