压裂车动力系统隔振优化研究

针对石油压裂车柴油发动机和压裂泵等动力系统的振动问题,提出了一种隔振系统参数优化方法。该方法的优化目标为提高柴油发动机和压裂泵等动力系统的解耦率,依据线性规划理论方法中的多目标到达法以及解耦优化理论,并采用MATLAB自带的fgoalattain函数来优化隔振系统的参数,通过改变物理参数和悬置原件的结构来提高系统的隔振效果。最后,通过时域仿真对优化效果进行了验证。

Research on Vibration Isolation Optimization of Power System for Oil Fracturing Vehicle

Aiming at the vibration problem of diesel engine and fracturing pump and other dynamic systems for oil fracturing vehicle,a parameter optimization method of vibration isolation system is proposed.The optimization goal of this method is to improve the decoupling rate of diesel engine and fracturing pump.According to the multi-objective arrival method and the decoupling optimization theory in the linear programming theory method,the fgoalattain function of MATLAB is used to optimize the parameters of the vibration isolation system,and the vibration isolation effect of the system is improved by changing the physical parameters and the structure of the originals.Finally,the optimization effect is verified by time domain simulation.
