Design of the test facility for bogie characteristics <br /> and its spring adjustment calculation<br /> <br />
Journal Title: Science Paper Online - Year 2006, Vol 1, Issue 5
Abstract
In this paper, according to characteristic of the bogie of Shanghai's A-type subway, the detailed mechanical schemes of the test rig and the measuring-system were put forward. The measuring-scheme includes the selection of the test system sensors and data processing modules, the interface processing between the single-chip microcomputer and computer, and the control system design. The hydraulic pressure system was designed. The test of wheel load, the body loading simulation, the measurement of the inner-side distance, the wheelbase distance and the primary spring stiffness, and padding and spring adjustment were carried out. The automatic spring adjustment system was designed for the test rig. The paper put forward a model to calculate spring adjustment to ensure that each wheel of the bogie has consistent weight. The computer code for the calculation of padding and spring adjustment was developed. So the ultimate padding size can be obtained automatically with the code. Windows of the system operation flow, control and detected systems were designed, and also the template of test reports was given in the present paper.
