Abstract

The torsional vibration is an important component of the fracturing pump truck, and it is also one of the important sources of the vibration noise. It is necessary to study the control of the torsional vibration of the fracturing pump crankshaft system. In this paper, a torsional shock absorber with silicone oil damping is designed for the fracturing pump crankshaft system to reduce the torsional vibration of the system. The inertia ring of the torsional shock absorber is designed by the empirical method. The preliminary parameters of the torsional shock absorber are obtained and the appropriate type of silicone oil is selected. Then, based on the numerical method and the standard particle swarm optimization (PSO) algorithm, the torsional vibration responses of the system before and after optimizing the torsional shock absorber are analyzed and compared. The statistical results indicate that the optimal torsional shock absorber is more effective for the torsional vibration reduction of system.
