加伍德式举升机构的优化设计

Optimun Design of Gawood Type Lift Mechanism

运用一般力学法则及解析法,推导出加伍德式举升机构举升运动规律的数学模型,并对该机构的运动特性进行了分析和合理的评价。用模式搜索法借助微机优化机构的几何参数。

The paper deduces a mathematical model for the movement pattern of Gawood's liftmechanism by using the common laws of mechanics and analytics. An analysis and a proper evaluation to themovement characteristic of the mechanism are given based on it. The geometrical parameters of the mecha-nism have been optimized by means of mod-search method with microcomputer.
