Design and Simulation of Hydraulic Braking System for Loader Based on AMESim

摘要

The loader develops towards the direction of heavy haul and high speed intellectualization, and puts forward higher requirements for its braking system. The power braking system is widely used in the field of engineering equipment due to its superior braking performance and reliability. Based on the analysis of the working principle of the hydraulic braking system, this paper establishes the mathematical model of the hydraulic braking system, and establishes the simulation model of the hydraulic braking system using the AMESim simulation platform, and carries on the simulation analysis to it. The results show that the pressure rise time is 0.1 s, the pressure drop time is 0.1 s when the friction disc contacts with the brake disc, and the brake pressure rise can be divided into three stages when the brake disc is unloaded; the accumulator can perform about 4 brakes until the next filling, and the piston reaches the limit position within 0.1 s. 0.8 mm..
