摘　　要：通过对正三角形、正多边形以及椭圆的转动运行轨迹探究得出:只要设计出适当的路面和汽车前后车轮轴心的距离,轮子是三角形、凸多边形和椭圆形状的汽车可以平稳行驶,并且求出一般结论,光滑封闭曲线形状的车轮可以平稳行驶。Through the studies of locus of moving wheels of equilateral triangle, regular polygon, and ellipse, it is declared： as long as the road and the distance of axis of front wheel and rear wheel of a car are proper, the cars with the wheels of triangular, convex polygon and elliptical shapes can run smoothly. And the general conclusion is obtained that the wheel with the shape of smooth closed curve can be smoothly running.

关 键 词：车轮 正三角形 正多边形 椭圆 光滑封闭曲线
