摘要
为进一步探寻XTR260硬岩掘进机双螺旋截割头部位的优化路径,结合该部位的运行工况与设计图纸,应用Pro/E三维建模软件建立其实体模型;应用有限元分析软件ANSYS和力学分析软件LS-DYNA,对其在不同螺旋升角参数下的力学性能进行初步分析.分析结果显示,当螺旋升角为14°时,截割头能够同时在钻进与横切两种截割工况下均具有较优的性能.该研究结果将为今后的硬岩掘进机双螺旋截割头的参数设计优化提供一定的参考借鉴.
In order to further explore the optimization path of the double screw cutting head part of XTR260 hard rock roadheader,combined with the operating conditions of this part and the design drawings,firstly,we applied Pro/E three-dimensional modeling software to establish its solid model;and then,we applied the finite element analysis software ANSYS and the mechanical analysis software LS-DYNA to carry out a preliminary analysis of its mechanical properties under different parameters of the helix angle of lift,which shows that when the helix angle of lift is 0.5mm,the mechanical properties are affected by the helix angle of lift.The results show that when the helix lift angle is 14°,the cutting head can have better performance under both drilling and cross-cutting cutting conditions.It is expected that the results of this study will provide a certain reference for the optimisation of the design parameters of the double screw cutting head of hard rock roadheaders in the future.
