摘　　要：本文基于人体膝关节的解剖特征,建立了人体下肢在矢状面内运动时,膝关节啮合的运动协调约束方程。这些运动协调约束方程,包含了运动膝关节股骨与胫骨相啮合时的滚动和滑动两种运动。它对于建立仿真人体下肢的生物动力模型是非常重要的。In the paper, based on the anatomical characteristic of the human knee joint, the geometric and kinemetic compatibity constraint contact conditions of the relative motions between the femur and the tibia in the sagattal plane, when both the femur and the tibia are motions, are established. These contraint contact conditions are necessary and important for establishing an anatomically-based biodynamic model of the human lower extremity. They include both the rolling and the sliding lotions of the articulation between the femur and the tibia.
