Finite Element Analysis and Optimal Design for the Derrick of Workover Rig

Abstract:

It proposed the finite element analysis to the derrick of workover rig in the paper. The stress distributing rule of derrick has been found, based on the finite element analysis of established derrick model. It analyzed the reasons for the effects of derrick thigh stress due to the derrick sustentation disposal format, the function of doorframe structure and the producing of dangerous section. The optimal derrick structure has been made up after calculating the derrick working stress, stress state and displacement measure.
