Steering System of a Lifting Robot Vehicle and its Dynamic Performance 890097

Paper illustrates a steering system of a lifting robot vehicle which is used for assembling and disassembling the active wheel of blower mill in power station. The whole steering system is controlled by a microprocessor. The axles of the four wheels are driven hydraulically. Proportional valves, which are controlled by the output signals of microprocessor calculated from the rotation angle of steering wheel, are used to control the flow into the cylinder. The step response of the system is calculated by digital simulation and the calculated result is compared with the experimental result, They are close to each other.
