Because of special geometry structure of three-cone bit, the top of formation will form a tri-spine well bottom while drilling with three-cone bit the drill string. It is the tri-spine well bottom that leads to the axial harmonic of vibration when the bit revolves a round and the three concavo-convex heave of bit and formation result in one time (1×rpm),two time (2×rpm), three time (3×rpm) turning table speed.

高岩由于三牙轮钻头的特殊几何结构，钻进过程中在岩层顶部容易形成一个三脊状井底，正是这一三脊状井底，当钻头旋转一周时钻柱轴向三次凸凹变化，由此在轴向产生1倍、2倍和3倍及其更高次倍于转盘转速rpm的谐波振动。

首先，对软件需求做了深入的分析，通过数据流图和数据字典与用户进行沟通，了解用户对系统的功能要求等；其次，介绍了软件设计的过程，分为三纵三横，三纵即：概念结构设计、逻辑结构设计、物理设计三个阶段，三横即：表现层设计，业务层设计和数据层设计。

First, I have made thorough analysis to the software demand, carried on the communication through the Data Flow Diagram and the data dictionary with the users in order to get the system function request of users and so on. The next, I have introduced the process of software design, which is divided into three verticals and three horizontals. Three verticals are the concept structural design, the logical organization design and physical design. Three horizontals are the representation layer, the operation layer and data layer.
