| 減振型板式軌道合理剛度動力分析(50 卷) |
| 英文標(biāo)題 |
| Dynamic analysis on rational rigidity of vibration-reducing slab-type track |
| 摘要 |
| 為了探明減振型板式軌道結(jié)構(gòu)的合理剛度及其匹配關(guān)系，應(yīng)用有限元分析軟件建立了梁—實體動力學(xué)模型，并結(jié)合工程實際確定了軌下剛度和軌道板下剛度取值方案。在模擬落軸試驗沖擊荷載作用下，分析了減振型板式軌道結(jié)構(gòu)的動力響應(yīng)。結(jié)果表明，減振型板式軌道的扣件合理靜剛度為3 |
