摘要
针对于钻头的有限元分析很好的解决了以前只能利用大量的实际钻削实验才能得到的实验数据这一问题。利用有限单元法,实验可以通过计算机进行仿真,节省了大量时间和占用机床时间,节约资金并且实验数据更加可靠,对生产实际具有重要意义。现在,钻头在生产环节的使用相当的广泛。针对钻头的动静态分析,通过修磨钻头,更改其结构参数,优化和改善其结构尺寸,来提高钻头寿命和确保加工质量。通过模态分析,求出钻头的固有频率,在实际加工过程中避开固有频率,以免共振,确保加工质量。
Aiming at the finite element analysis of the bit,the problem of the experimental data can be obtained by using a large number of real drilling experiments.By using the finite element method,the experiment can be carried out by computer simulation,save a lot of time and take up the machine time,save money and the experimental data is more reliable,it has important significance to the production.Now,the use of bit in the production process is quite extensive.For the dynamic and static analysis of the bit,the structure parameters,the structure parameters,and the structure size of the drill bit can improve the bit life and ensure the machining quality.Through the modal analysis,the natural frequency of the drill is calculated,and the natural frequency is avoided in the actual machining process,so as to avoid resonance and ensure the quality of processing.
