摘要
以中间加持的螺栓紧固型针板作为主要的研究对象,利用计算机仿真技术,研究针板相关工艺参数对针刺过程中的针板变形情况。首先将针板按照针板材料、幅宽长度、植针密度等分为20块参数不同针板,并使用CAD制图软件制成相应的三维模型;然后通过物理学非惯性系的相关规则,引入惯性力,将针刺机的针板、刺针、针梁视为滑块;最后通过导入针板模型,网格划分制作有限元模型、相关力学载荷加载等操作后进行ANSYS Workbench有限元仿真模拟实验。结果表明:针板变形与植针密度呈正相关且增长趋势将随着植针密度增大而愈加明显;镁合金针板的形变值和应变值均高于铝合金针板;针板幅宽长度的增加将直接增大针板的变形量。
The bolt-fastened needle plate with intermediate support is the main research object.Using computer simulation technology,Study the process parameters of the needle plate to determine the deformation of the needle plate during the needling process.Firstly,the needle plate is divided into 20 different parameters according to the needle plate material,the width and the length of the needle,and the corresponding three-dimensional model is made by using CAD drawing software;Then,through the relevant rules of the physics non-inertial system,the inertial force is introduced,and the needle plate,the lance needle and the needle beam of the needle punching machine are regarded as the slider;Finally,the ANSYS Workbench finite element simulation experiment was carried out by introducing the needle plate model,meshing the finite element model and related mechanical load loading.The results show that the deformation of the needle plate is positively correlated with the density of the needle and the growth trend will become more and more obvious as the density of the needle increases.The deformation value and strain value of the magnesium alloy needle plate are higher than those of the aluminum alloy needle plate;An increase in the width of the needle plate will directly increase the amount of deformation of the needle plate.
