摘要
针对大型挖掘机铲齿的结构,利用MARC/metant软件进行模拟分析,提出了结构优化设计的方案。利用正交试验方法,研究应用于铲齿的低合金耐磨钢的制造工艺,获得了合理的热处理工艺。实验结果表明,经过930℃淬火及220℃回火处理后,实验材料具有较好的综合性能,硬度为46 HRC,低温冲击韧度可达到47 J/cm^2。
The bucket tooth structure of large excavator was analyzed by means of the MARC/metant softs.An optimum structure design was suggested.By orthogonal experimental method,the heat treatment process of the designed low-alloyed steel was researched.The results show that there is an excellent combination properties of wear resistant steel treated after930 ℃ quenching and 220 ℃ tempering,the hardness is 47 HRC,the low temperature impact ductility is 47 J/ cm^2.
