A Study on the Air Spring Suspension Morphologies of EMUs Bogie
Based on the pneumatic model of air spring and the dynamics MBS model of EMUs, the dynamics behaviors of EMUs in the2-point configuration and 4-point configuration were studied contrastively. What’s more, two improved suspension morphologies wereanalyzed, including the 4-point configuration with ant...

| Summary: | Based on the pneumatic model of air spring and the dynamics MBS model of EMUs, the dynamics behaviors of EMUs in the2-point configuration and 4-point configuration were studied contrastively. What’s more, two improved suspension morphologies wereanalyzed, including the 4-point configuration with anti-rolling bar and the front 3-point configuration with the controlled differential pressurevalve. The results of the research indicated that: the EMUs with 2-point and 4-point configurations possed the similar dynamics behaviors;the 4-point configuration with anti-rolling bar could ensure the running safety of EMUs in the fault cases; the front 3-point configuration withthe controlled differential pressure valve could improve the EMU’s ability of passing curve in certain extent. |
