Abstract

Fracturing truck is the core equipment in shale oil and gas exploitation. The operation environment is harsh. As the main bearing structure of the fracturing truck, the frame should have high efficiency and reliability to ensure the stable operation of the fracturing truck. Therefore, a frame model of the all-electric fracturing vehicle was established in this paper, and the load spectrum of the frame was simulated with white noise load when the fracturing vehicle was running on uneven road surface, and the finite element transient analysis of the frame was carried out. Then, a five-block diagram of fatigue analysis was established by using ncode Design-Life software, and the fatigue analysis results of the fracking truck frame were calculated according to the linear cumulative damage theory and S-N material characteristic curve. The research provides an effective reference for the detection of the fracking truck frame, so as to ensure the running stability of the fracturing truck.
