| Abstract: | Aiming at the problem that the energy recovery rate of hydraulic braking system was low, the regenerative braking system in the combined braking system was analyzed by using a hybrid loader as the prototype. The main parameters affecting the energy recovery rate of the system were optimized by using genetic algorithm, and the optimized system was simulated in the vehicle simulation model for verification. The simulation results show that the energy recovery rate of the vehicle is improved greatly after the system optimization, and the purpose of energy saving and emission reduction is achieved. |
