abstract = {<p style="text-align: justify;">Taking vibration converter of intelligent damper for drill strings as the
 study object, this paper analyzes the influential factors of motion state
 of the ball and conducts an explicit dynamics simulation by establishing a
 mechanics model of vibration converter. The study basis is Newton&#39;s laws of
 motion, D&#39;Alembert&#39;s principle and Hertz contact theory. And we use world
 coordinate system, rotating coordinate system and Frenet coordinate system
 to deduce kinematics equations of vibration converter. The ultimate result
 demonstrates that the axial velocity and maximum contact stress change with
 the increment of ball diameter and helix angle. It also proves the validity of
 our derived kinematics and mechanical models and provides a good consultant
 value for the design and theoretical arithmetic of vibration converter for
 intelligent damper of drill strings.</p>},
