Study On Coordination Control System Of Load Lateral Deviation And List Of Tire Test Machine

The automobile low-speed tire test machine is a simulated motor in a state of low-speed movement, acquisition tire various parameters in different state of movement and force from the test equipment. This equipment mainly consist of implementing agencies, hydraulic circuit and electronic controllers and computer control system, that make up a closed-loop system to achieve perpendicular load, lateral deviation and list movement. After synthesizing numerous related literatures and reference materials home and abroad, the automobile low-speed tire test machine of domestic and oversea system is summarized and the merit and shortcoming is analyzed. The studying direction is decided through comparing domestic products and overseas products.In this paper, the equipment main hydraulic control systems are used in the structure of valve controlling unsymmetrical cylinder. Based on the transfer function of valve controlling unsymmetrical cylinder, established the mathematical model of perpendicular load, lateral deviation and list movement. According to practical situation of tow system, these models were studied separately using MATLAB7.0/simulink software, and did the sina movement analysis with the simulating result. From the simulating result found the problem and then through the pressure compensation improved mathematical model and made an ideal simulation result. Through this control method, the coordination control system programs are found and proved that the methods advanced in this conclusion is effective from the date of this equipment.We can draw the conclusions that the methods are fit for the rest coordination control system of the automobile low-speed tire test machine.
