挠性剑杆传剑机构的动力学研究

本文提出了一种把我国1515—7″织机改造为挠性剑杆织机的设计方案。对这种传剑机构进行了较全面的动力学分析,包括织机回转不匀的近似计算、弹性动力学模型的简化和传剑机构一阶固有频率和主振型的近似计算等。本文对研究其他类似的剑杆织机动力学特性具有一定的参考意义。     

An Optimization Design of a Weft Insertion Mechanism for Rapier Looms

By analyzing a combined and spatial 6-bar linkage weft insertion mechanism, its practical model for optimization design is set up and the modification of penalty strategy is put forward so that the genetic algorithm can be better used in optimization design for mechanisms with non-linear constraints. The design result is discussed.
