摘要
钻机是现代煤矿井下采煤的重要工艺装备。钻机正常工作时,动力给进部分受力复杂,工作环境苛刻。为保证产品质量及可靠性,使用有限元分析软件ANSYS专门对给进模块进行了应力分析及振动模态计算。通过计算,得到了ZDY2000L型钻机给进模块在极限工作状态下的局部应力最大值为60.809MPa及导轨刚度变形最大值为0.029 7mm,发现所设计的产品在降低用钢量的情况下,能够同时保证结构局部的强度小于215MPa的要求及整体刚度变形小于0.1mm的要求。最后,对给进结构进行了必要的振动模态分析,得到各阶频率值,从而为改善系统的力学性能提供了理论依据。
The Drilling machine is a modern coal mining technology and equipment of mine-coaling. When Drilling machine work properly, the power feed part is under the complicated forces, and the working environment is harsh. In order to ensure product quality and reliability, using finite element analysis software ANSYS dedicated feed module the stress and vibration modes of calculation. By calculating the results obtained ZDY2000L rig feed module in a state of extreme working stress distribution and rail stiffness and deformation values and found that the design of the product in the case of reducing the amount of steel, while ensuring the strength of the structure of local requirements and overall stiffness deformation requirements. Structure necessary vibration modal analysis of the natural frequencies has been submitted so as to provide a theoretical basis for improving the mechanical properties of the system.
