基于可控精度法的开铁口机机构设计

Design of the Tap- Hole Drill Mechanism based on Selective Precision Synthesis

可控精度综合法是一种实用、高效的平面杆机构的设计方法,它使所设计的机构在各个离散点都有不同的任选精度。由于引入了并向量的结构,大大简化了优化过程,尤其是对于有相对固定点的一类杆机构的综合。通过对高炉开铁口机构基本尺寸的优化设计验证了此方法的优越性。并利用Matlab建立了问题的数学模型,进行了一系列的分析计算,实现了杆机构轨迹的优化设计。

The selective precision synthesis （SPS） is a practical and efficient design method for planar mechanism. It can make the design of the mechanism in each discrete point has a different op- tional accuracy. Due to introduction of dyadic construction, the optimization process is greatly simpli- fied, especially for the synthesis of planar mechanism which has relative fixed points. The superiority of this method is tested through the optimization design to the size of blast furnace tap--hole drill mechanism. And its mathematical model is established by using Matlab. Through a series of analysis and calculation, the trajectory optimization design of bar mechanism is realized.
