In order to explore the trailer suspension system with high dynamic response and low energy consumption, a new type of trailer hydraulic suspension system is constructed by using a combination of load sensing hydraulic system and accumulator. The suspension system of the load sensing hydraulic system enables the output pressure and flow to automatically adapt to load requirements, improve system efficiency; and energy storage can greatly improve the system’s dynamic response. According to the composition of the system, a mathematical model of the hydraulic suspension system of a mining car is established and the simulation analysis is carried out by using MATLAB software. The simulation results show that compared with the traditional suspension system, the hydraulic suspension system has better dynamic performance and energy saving effect, which is beneficial to the further research of the hydraulic suspension system of the tub.
