The bottom structure of the slipper pair in a hydraulic transformer plays a crucial role in improving the overall efficiency of the hydraulic transformer.Faced with the complex operating conditions of the hydraulic transformer,a multi-objective particle swarm optimization algorithm is used to optimize and design the bottom structure of the slipper pair.Firstly,a complex force analysis diagram of the slipper pair in the hydraulic transformer is established,and the dynamic equations of the slipper pair are derived.Then,the AMESim leakage and friction models of the slipper pair in the hydraulic transformer are constructed.Subsequently,a multi-objective particle swarm optimization algorithm model is established,with the minimum leakage and friction torque of the slipper pair as the optimization objectives.The bottom parameters of the slipper pair are optimized,and the optimized bottom parameters of the slipper pair are obtained through the optimization algorithm.Finally,the results are obtained through model simulation experiments.The optimized bottom structure parameters of the slipper pair significantly reduce the leakage and friction torque losses of the slipper pair,greatly improving the efficiency of the slipper pair.
