Optimization Design of Subframe Structure of High-Power Fracturing Vehicle
In the face of the increasingly frequent complex formation and ultra-deep well operating environ-ment of more than 5000 meters,the development of fracturing trucks equipped with high-power fracturing equip-ment has become an important development trend.In this paper,Optistruct module of Hyper Works is used to optimize the topology of fracturing truck subframe based on SIMP variable density method.Under the topology optimization results of single working condition and single objective,a multi-objective multi-working condition topology optimization mathematical model based on compromise programming method was established to obtain the topology optimization results after the flexibility minimization and low-order dynamic maximization of fractu-ring truck subframe under various static working conditions,and then the fracturing truck subframe model was reconstructed according to the material distribution cloud map.The results can be used to improve the subframe structure of fracturing truck to increase its bearing capacity,shorten the development time and reduce the cost.
