| 摘 要： | 分析了液体在涡轮钻具叶片表面流动规律,得出高效率涡轮钻具叶片型线设计应该满足的必要条件.由此提出了一种满足条件的叶片型线模型,并根据叶片的几何关系给出了数学模型的求解方法,为提高现有涡轮钻具的工作效率提供了一种参考叶型.并应用Pro/E进行了三维特征建模,基于这种参数化的模型,直接和高级语言编写的应用程序接口,可实现自动修改实体特征.在此基础上,编制了涡轮钻具叶片设计软件,实现了涡轮钻具叶片的自动设计,提高了涡轮钻具的设计质量和设计效率.

| Abstract: | Based on the research on the motion law of the drilling fluid along the blade, the necessary condition of the blade shape for a high efficiency turbodrill is obtained. Hence a mathematical model how to design a blade shape has been put forward, and the solution method of the model is obtained, which helps to design a high efficiency turbodrill. What's more, a 3 dimension model of the blade has been set up using Pro/E software, which can link with the advanced computer language by a interface routine and modify the 3-D blade model automatically. Based on the theory, a software has been compiled to design the blade automatically, which can improve the design efficiency and the design quality of the turbodrill. |
