CSO Intelligent Optimization of Drag Torque Parameters of Wet Brakes Based on the SSA-BP Approximate Model
To solve the engineering problem of power loss in wet brakes under non-braking conditions
taking into consideration the influence of the lubricating oil in the clearance of friction pairs on the drag torque of the friction pair
making use of the strong nonlinear fitting ability of the sparrow-search-algorithm-back propagation (SSA-BP) neural network
and taking the no-load operating condition of wet brakes as the input variable and the drag torque as the output variable
an approximate model of wet brakes is established. Compared with the traditional BP model
the prediction accuracy is obviously improved
which can meet the needs of practical engineering. In order to obtain the minimum drag torque
the working parameters are searched and optimized through chicken swarm optimization (CSO) intelligent algorithm
and the best working condition of the wet brake is obtained. The experimental results show that the drag torque and power loss between the friction pairs after optimization are significantly lower than those before optimization. This study provides theoretical research basis and engineering practice experience for the further optimization of wet brake structure.
