摘要
WC5型防爆胶轮车应用于煤矿井下作业,该车在某煤矿作业时发生主梁断裂。本文旨对主梁进行强度分析,确定其破坏原因,通过分析破坏原因提出可行的改造方案。借助UG中的实体建模和装配建模两个模块完成了车架CAD模型的建立,并简化了车架的几何模型,建立了有限元模型。应用有限元软件ANSYS对WC5型防爆胶轮车车架进行强度分析,确定了其破坏原因,找到主梁发生断裂初始位置,在满足主梁刚度和强度的基础上提出了初步的改造方案,通过对改造后梁的有限元分析表明改造方案是可行的。
WC5 flameproof rubber-tyred vehicle is used under the well of coal mine,when the vehicle worked under the well,the frame distroyed.The intensity analysis to WC5 flameproof rubber-tyred vehicle frame and the reason of distroyed are given and provided a preliminary design project are the main works in this paper. The CAD model of the frame is set up by solid model and assembled model in UG, whose geometric model is simplified and the finite element model is established.The intensity analysis toWC5 flameproof rubber-tyred vehicle frameis studied by ANSYS, thereason of distroyed and the initial position of frame distroyed are given,furthermore provided a preliminary design project.Feasible design project is approved by finite element analysis of rebuild frame.
