摘要
为了降低钻头设计和改进效果的不确定性,同时减轻设计人员劳动强度并提高钻头设计效率,采用NXOPEN和UFun混合编程技术研发了钻头力平衡校验软件。该软件使用UG自带的面积、弧长、体积测量功能取代复杂的轨迹方程计算,并集成了异形切削齿替换功能,显著降低了钻头力平衡校验过程中计算复杂度,有效解决了异形齿钻头设计出图速度慢的问题。针对不同砂砾岩厚度设计了两款心部寿命不同的钻头,在适用条件下都表现出很好的使用效果。通过对钻头设计时心部位置切削力和切削体积的数值对比分析,很好地解释了钻头寿命差异的原因。两款钻头的使用效果验证了该软件设计过程的确定性和软件研发的必要性。研究结果可为钻头设计提供参考。
To reduce uncertainties in bit design and improvement effectiveness,while also lowering workload of designer and enhancing design efficiency of bit,a bit force balance verification software was developed using NXOPEN and UFun mixed programming techniques.Using the area,arc length and volume measurement functions built in UG to replace complex trajectory equation calculations,and integrating the special-shaped cutter replacement function,this software significantly reduced the computational complexity in the process of bit force balance verification,and effectively solved the problem of slow drawing speed in the design of special-shaped cutter bit.Two bits with different core lifespans were designed for different thicknesses of glutenite,and both they demonstrated excellent performance under applicable conditions.Through numerical comparison and analysis of cutting force and cutting volume at core location during bit design,the reasons for the difference in bit life were well explained.The application effect of the two bits verified the design process determinacy of the software and the necessity of the software development.The research results provide reference for the design of bit.
