Quality monitoring of tractor hydraulic oil based on improved PSO-BPNN
In order to effectively monitor the quality of tractor hydraulic oil and ensure the smooth operation of the tractor hydraulic system,a monitoring method for tractor hydraulic oil quality was designed by using improved PSO-BPNN.Firstly,in order to study the deterioration of tractor hydraulic oil quality,different proportions of hydraulic oil samples were prepared on the basis of new hydraulic oil.Subsequently,a tractor hydraulic oil quality monitoring test device was built,and the viscosity,dielectric constant,and temperature of the hydraulic oil were collected and monitored based on the test device.Secondly,a tractor hydraulic oil quality monitoring model by using improved PSO-BPNN was designed.The model utilized the PSO algorithm with sine adjusted inertia weights to optimize the weights and initial threshold values of BPNN,improving the convergence efficiency of the model.Finally,for verifying the feasibility of the hydraulic oil quality monitoring method by using improved PSO-BPNN,a comparison was made with the tractor hydraulic oil quality monitoring models by using traditional BPNN and standard PSO-BPNN.The comparison results show that the tractor hydraulic oil quality monitoring method by using improved PSO-BPNN has a fast convergence speed,with a monitoring accuracy of 97.78%,which can provide reference for optimizing the tractor hydraulic oil quality monitoring method.
