摘　　要：采用多项式方程描述三边形压实轮的外廓曲线,对压实轮的运动轨迹进行了分析,得到了压实轮重心坐标的变化规律。根据运动分析得到三边形压实轮对地面的夯实能量分别由平动动能、转动动能和重力势能构成,分析结果可用于压实轮的结构设计与冲击能量评估。Multinomial equations are adopted to describe the profile of triangle shaped compacting drum. The kinetic track of the drum is analyzed. The variation regularity of the drum gravity center coordinates is obtained. According to the analysis, the compacting energy of triangle shaped compacting drum to the earth comes from horizontal movement kinetic energy, rotary movement kinetic energy and gravity potential energy. The analysis result could be used in the structure design of compacting drums and the evaluation for impacting energy.
