thesis
Taking a three-axle vehicle as the research object, the working principle of multi-wheel steering electronic control hydraulic system is expounded, and the steering resistance moment is analyzed in detail, which is the simulation of hydraulic system and its.
Steering system
The design provides a theoretical basis; The mathematical model of the basic components of the hydraulic system and the working principle of the hydraulic control valve are analyzed, the stroke of the hydraulic cylinder is calculated by geometric method, and the thrust of the steering hydraulic cylinder is calculated with reference to the vehicle parameters of the three-axle vehicle, which lays the foundation for the establishment of the hydraulic model in the next step. A variety of basic hydraulic control circuits are analyzed, and the pressure regulation circuit, outlet throttle speed regulation circuit and asymmetric actuator proportional speed regulation circuit are combined into a three-axis automobile steering hydraulic circuit. Using Easy5 software to model and simulate the steering system of three-axle automobile, change the parameters of hydraulic system, analyze the dynamic characteristics of the system, and summarize the influence law of parameter change on the dynamic characteristics of the system. The analysis method and corresponding conclusions adopted in this paper are of great significance to multi-axle vehicles in the future.
Steering system
This design has certain reference value.
