Design Of The Zj50/3150ldb Derrick And Finite Element Simulation Computation Analysis

As an important component of petroleum drilling machine, derrick is used to placing the lift equipment such as Crown Block, Traveling Block and so on ,and holding different loadings.So,the designing and structural analysis about derrick is always an important theme of the petroleum mining machinery research.First, through researching the domestic and foreign drilling machine derrick, carrying on the comparative analysis about the similar products and the overall analysis to the product design request,we completed the design of derrick ZJ50/3150LDB, established the basic parameters of the derrick, materials, the overall structure , the main derrick structure of the derrick, as well as the requirements of the manufacturing process.Second, based on ANSYS software ,we studied the finite element method in simulation ZJ50/3150LDB derrick machine structure analysis.Through the analysis about the derrick load and stress,we build up a derrick finite element analysis model, make a finite element simulation about derrick on the static conditions of the four typical conditions , and analysis of simulation results based on the strength of verification and optimization of the design; Set up well for the process of finite element analysis of the simulation to study the derrick or from different angle as well as the location of the lifting 'A'frame with the lifting strength,and then carry out the strength verification and optimization of the design; And set up a stable model for the finite element analysis of the simulation to study the derrick to maintain the stability of the critical load.Finally, we obtain safe and reliable conclusions in accordance with the design of finite element analysis and simulation analysis of the drilling rig derrick ZJ50/3150LDB well-designed.
