外文摘要：The connection performance of the large taper, multi-thread, variable pitch of screw threaded casing is researched by 3D finite element simulation on ANSYS Workbench. The 3D finite element model is created precisely. The stress distribution on the teeth of three kind variable pitch of screw threaded structure is studied by using the static structure of the contact analysis module. Contrasting stress distribution of the variable pitch of screw with of the equal pitch of screw under the same working condition, it is validated that design principle for the variable pitch of screw connection is correct. The influence of changes in the amount of variable pitch of screw to the whole stress distribution on teeth is discussed. The results show that the force distribution on the teeth of the variable pitch of screw connection is more uniform than equal pitch of screw, and will improve the overall carrying capacity. This study has its practical value to improve the connective performance of the threaded casing and enhance the product quality of threaded casing.
