管道切割对开式钻铣机钻铣头强度分析

摘要

Milling head is the important actuator of divided milling machine.The strength value of milling machine has big affection in reliability when it working.Thus,the static and modal analysis used finite element software ANSYS has important meanings.The geometric model of milling head was budded by 3D software Pro/E and tested the interference of the model.The finite element was constructed through the connector of Pro/E and ANSYS and made modal and static analysis through ANSYS.The results of dynamic simulation show that there is no interference produced.The results of modal analysis show that there is no resonance phenomenon produced.At the same time,the results of static analysis show that the stiffness and strength is satisfied.Theoretically,the results of software provide references for the structure and optimizing design of the machine.%钻铣头是管道切割对开式钻铣机的重要执行元件,其强度的大小对钻铣机工作的可靠性有着非常大影响,应用有限元软件ANSYS对其进行静态和模态分析有着重要的意义.通过三维软件Pro/E建立钻铣头的几何模型,并进行运动仿真检验其是否产生干涉,利用Pro/E软件和ANSYS软件的接口将几何模型导入ANSYS软件中,运用ANSYS软件建立有限元模型进行钻铣头的静态和模态分析.运动仿真结果表明模型未产生干涉,有限元模态分析结果表明无共振现象产生,有限元静态分析结果表明刚度和强度满足要求,应用三维软件和有限元软件从理论上为设计的合理性提供了依据,也为优化设计提供了参考.
