建立凸轮廓线外凸性判据的一种新方法──支撑函数法

A new method to set up the convexity criterions of cam Outlines-support function mathod

本文通过引人积分几何中＂支撑线＂和＂支撑函数＂的概念，揭示出其在平底从动件盘形凸轮机构中生动的几何直观背景，提出了一种简单通用、行之有效地建立凸轮廓线外凸性判据的新方法──支撑函数法。

Through introducing the concept of'support line' and 'support function' in integral geometry this paper revealed its vivid geometrical audio-visual background in disc cam mechanism with flat bottomed follower. A kind of new,simple,universal,and effctive methed to establish the covexity criterions of eam outline -- 'support function method'-- has been advanced.
