Research on Structure Design of Deep Hole Drill Based on the SolidWorks Simulation

根据激光焊接工艺的独特性,利用SolidWorks对深孔钻头钻齿结构进行初始建模,并根据SolidWorks自带的nSimulationXpress仿真模块加载失效模拟的应力分布情况分析结果进行结构设计优化,令其能在既定工况负载下保证不发生断齿失效的同时最大化的提升所设计深孔钻头的理论使用寿命。通过加载实验及力学推算完成了模拟优化结果的验证,证明了计算机模拟优化辅助设计在钻头设计中的可行性。进一步通过SolidWorks的nSimulationXpress仿真模块完成对钻头的胎体结构优化设计。

Based on the uniqueness of laser welding, the drill bit structure of deep hole drill has been initially modeled by Solidworks. Meanwhile, the structure design of deep hole drill has been optimized according to the analysis＇result of the stress distribution simulated by the nSimu- lationXpress Simulation Module Loading Failure System which comes with SolidWorks. There- fore, the theoretic service life of the deep hole drill has been extremely increased under the condi- tions that drill bit works normally under the given load without any damage or failure. The sim- ulated optimization result has been tested through loading experiment and mechanical calcula- tion, thus the feasibility of computer aided simulation optimization design in drill bit designing has been proved. The matrix structure optimization design will be also conducted through the nSimulationXpress Simulation Module of the SolidWorks.
