摘要：
Double shoulder drill pipe joint (DSJ) is a novel thread structure which appears in recent years. Its strength reduced efficiently while the structure design is not appropriately, for the DSJ's mechanical behaviors weren't well studied. In this paper a 3D whole structure finite element model of DSJ was established based on the Principle of Virtual Work, and validated the model's computing results by experimental results. The authors analyzed the stress and strain distribution with the 3D whole structure finite element model's computing results under torque moment, compression force, tension load, and bend moment. And then acquired the DSJ's mechanical behaviors under each load. The research works of this paper refer accordance to recognize and design the DSJ. © 2019 Southwest Petroleum University
