AI Technical Summary
Existing testing methods for air spring control units (LSTs) in maglev trains require on-board testing, which is inconvenient, inefficient, and prone to false alarms due to difficulties in air tightness testing, affecting the accuracy of test results. Furthermore, the frequent inflation and deflation processes exacerbate wear and tear on the air compressor and increase maintenance costs.
An independent testing device for the air spring control unit (LST) of a maglev train was designed, including an air source, an adapter board, an air tank, a control box, and a pressure measuring device. It can independently test the LST on the ground. The air tightness test is achieved by controlling the opening and closing of the air inlet valve through the control box, avoiding interference from environmental leaks. Multiple LSTs can be tested in parallel to improve efficiency.
It enables efficient, convenient and accurate LST detection, improves testing efficiency, reduces false detection rate, reduces dependence on trains, extends the service life of air compressors, and reduces maintenance costs.
