Abstract:
According to the fact that the make-up torque curve of the premium connection of the oil casing is influenced by the combination of deviations such as the friction coefficient,the thread diameter,the thread taper,and the sealing surface diameter etc.,based on the Python Language,an Abaqus premium connection FEA module is developed. The module is capable of hi-efficiency FE simulation of the entire process from make-up to screw up yield of the connection. The results can be integrated as per the make-up torque curve model to get the make-up torque,and then draw the torque curve. In accordance with different connection surface treatments and thread compound types as well as the actual test result,the friction coefficient curve is calibrated,which has very high operability and accuracy in the actual application. The above mentioned module as developed features being easy to inherit,expand and upgrade.
