摘要: 为了解决高速经编机槽针六连杆机构的动力学分析,减少运动冲击,提高经编机高速运动的平稳性,采用多变量柔性机构运动弹性动力学分析(KED)方法,对槽针六连杆机构进行了弹性动力学分析。基于UG建模技术,对槽针六连杆机构进行了建模分析,系统地研究了槽针在高速运动时的柔性变化;并运用UG模拟了槽针在不同运动条件下的位移、速度、加速度的变化状况,实现了对槽针六连杆机构的计算机运动仿真;该方法验证了成圈机件KED分析方法的正确性,为槽针六连杆机构的结构设计与优化提供了理论分析的依据。

Abstract: In order to solve the dynamical analysis of slot needle's six-bar linkage in high speed warp knitting machine, reduce the impact of movement, the high-speed movement’s smoothness of warp knitting machine is improved. The Kineto-elastodynamic analysis (KED) method of multivariate flexible mechanism is applied to analysis of slot needle's six-bar linkage. The analysis of structural modeling is presented in the slot needle's six-bar linkage based on the technique of UG, and the flexible variation of the slot needle is systematically studied in the high-speed movement; the UG is applied to the changing situation of slot needle's displacement, velocity, and acceleration which simulated in different conditions of movement; The correctness of the KED analysis methods of knitting elements is verified, the basis of theoretical analysis is provided for slot needle's six-bar linkage of knitting elements structural design and optimization.

Key words: high speed warp knitting machine, slot needle, six-bar linkage, elastodynamics, UG simulation
