Study of computer simulation on top driving well drilling device

A preliminary study was made on the commonly used software Pro/E, ADAMS and ANSYS for computer aided modeling, simulation and analysis in mechanical systems and on the interface standard among them. A set of practical route diagram and overall frame for making the modeling, simulation and analysis of mechanical system was summarized. A clarification was made on the problems ought to be noticed in the modeling, simulation and analysis on the top driving well drilling device. A designing study was made on the pipe-rod changing mechanism in the top driving well drilling device, and the continuous flexible module of connecting rod and discrete flexible module of connecting rod were integrated, and a tentative simulation and analysis were made upon it. The equivalent spring had been made for the raise-lifting system in the top driving well drilling device, and the discrete flexible module of drilling column was integrated and a preliminary simulation and analysis were carried out. The model of top driving device when starting drilling was established and the continuous flexible module of slide-way was integrated and a tentative simulation and analysis were also made.
