摘要: 在PRO/Engineer环境下创建牙轮、牙爪以及各个牙齿的模型,使用合理的连接将其装配并约束。然后在PRO/Engineer的Mechanism模块中,对三牙轮钻头设置载荷、约束及边界条件,确定初始条件,模拟钻头运动(包括钻头转动、牙轮传动及钻头整体向下运动),测量并输出牙齿上某一点位移、速度、加速度及空间运动轨迹等数据。对比分析牙轮上各齿如背锥齿、外排齿及内排齿等所取点的各种数据,并对不同参数组合情况下输出进行了分析和对比,得到三牙轮钻头牙齿在钻进过程中各齿的运动状况,为钻头的几何设计和性能设计提供了丰富的、有用的信息,对牙齿破碎岩石的力学模型和坑的模型建立有着重要的意义。

Abstract: Some reasonable connects are used to assemble these parts to create the 3D solid models of the cones, claws, and teeth with Pro/ENGINEER. In the Mechanism module of PRO/ ENGINEER, loads, constrains and boundary conditions fixed, the initial conditions are determined to simulate drilling bit operation (including bit and the teeth rotary movement,up and down movement of the bit). Some analysis definitions in the initial condition are created, and the displacement, velocity, acceleration and space movement trajectories of a given point on teeth are measured under this definition. Finally the data from characteristic points on the back cone teeth, gauge teeth, and interior teeth are analyzed. All different parameters combination are compared. The movement states of different rows of teeth are obtained under given conditions. The analytical results provide a wealth of information for geometry and performance design of tricone rock bits.

Key words: tricone rock bit, teeth, PRO/ENGINEER, kinetics, simulation
