| 提速道岔加長(zhǎng)型普通墊板強(qiáng)度分析(49 卷) |
| 英文標(biāo)題 |
| Analysis on strength of length-increased type common pad for speed up turnout |
| 摘要 |
| 軌下墊板的強(qiáng)度和耐久性對(duì)軌道安全穩(wěn)定運(yùn)行有十分重要的作用。通過對(duì)厚27 mm的提速道岔用加長(zhǎng)型鑄造墊板和鍛造墊板的力學(xué)分析，應(yīng)用ANSYS通用有限元軟件建立計(jì)算模型，檢算了鑄造墊板和鍛造墊板的應(yīng)力、位移和疲勞強(qiáng)度。結(jié)果均滿足要求。 |
