| Abstract: | It is steel spring and double-rod flexible positioning structure that is used on the bogie primary sus- pension of EMU CRH5A. The double-rod positioning is complicated,with several different rubber parts, which makes it difficult to calculate the positioning stiffness. This article shows the analysis on primary suspension double-rod positioning stiffness, gives the calculate formula. |
