| 3D軸焊接構(gòu)架式轉(zhuǎn)向架重車過曲線輪軌橫向力超標原因分析(26 卷) |
| 英文標題 |
| Analysis on the Reason of Larger Wheel/Rail Lateral Force for Loaded Car with 3D-axle Welded-frame Bogies during Negotiating |
| 摘要 |
| 根據(jù)轉(zhuǎn)向架結(jié)構(gòu)理論分析和動力學仿真計算，對3D軸焊接構(gòu)架式轉(zhuǎn)向架通過曲線時重車輪軌橫向力偏大的原因進行分析。認為3D軸焊接構(gòu)架式轉(zhuǎn)向架的主、副摩擦面摩擦系數(shù)偏大，使重車通過曲線時斜楔處于卡死狀態(tài)，輪對軸箱縱向呈剛性定位，從而導致重車過曲線時輪軌橫向力偏大。提 |
