以有限元分析与优化设计理论为基础,结合UG NASTRAN有限元分析软件,建立了经编机槽针床摆动臂结构的有限元分析模型,对其结构进行了静力学应力分析,利用应力分析结果作为优化设计的强度和刚度约束条件,建立了经编机槽针床摆动臂的数学模型,并对其进行优化。结果表明,在保证零件强度和刚度的前提下,通过改变主要设计尺寸参数,使结构的质量减轻了7.6%,从而有效提高了机构的运行速度。

In this paper,needle-bed warp knitting machine slot swinging arm structure of the finite element analysis model and static stress analysis of its structure are established,combined UG NASTRAN finite element analysis software based on finite element software and optimization theory.The mathematical model of needle-bed warp knitting machine slot swing arm is optimized with the results of stress analysis as the optimal design strength and stiffness constraints.The results show that the structure of the weight is reduced by 7.6% and the structure＇s speed can be improved by changing the size of the main design parameters in ensuring the strength and stiffness.
