摘要
掘进机的截割头作为关键部件,直接影响机器的整体性能。截齿分布、截齿数目等因素对截割效率、截齿的寿命及截割性能影响很大。采用SolidWorks建立截割头模型并使用仿真对新型59把截齿截割头的建模以及结构进行有限元分析研究,找出截割头的应力分布规律,并不断改进模型,使其在正常工作状态下所受的应力较小,且安全系数较大,满足材料的强度条件,能够适应工作要求。新型59把截齿截割头掘进机具有较强的实用价值,在开发应用方面具有一定的前景市场,可以有效节约设计成本和提高设计效率。
The road header cutting head as key components, directly influence the overall performance of the ma- chine, cutting teeth distribution, the number of teeth, and other factors to efficiency of cutting, cutting teeth life and cutting performance have very great influence. The established cutting head model by SolidWorks and use the finite element analysis by simulation, find out cutting head of the stress distribution law, and constantly im- proved model, can effective economy design cost and improve the design efficiency.
