几何作图法求取动点轨迹曲率中心

Determination of Curvature Center of Kinetic Point Path Using Geometrical Construction

本文运用刚体几何运动学基本原理提出几种求取连杆平面上动点运动轨迹的曲率中心及曲率半径的作图方法。它可直接在工程设计图纸上按照杆件图形所在位置画出而不需要通过计算。

This paper brings forth several construction methods for determining the curvature center and radius of the kinetic point path on the plane of the linkage. By using these methods, the curvature center and curvature radius can be represented directly on the design drawing in terns of the member figures without calculation.
