| 標(biāo)題 |
| CA砂漿彈模對(duì)框架板式軌道翹曲應(yīng)力的影響分析(51 卷) |
| 英文標(biāo)題 |
| Analysis about influence of cement emulsified asphalt mortar’s modulus of elasticity on framed slab track warping stress |
| 摘要 |
| 采用有限元分析法，對(duì)框架板在溫度梯度作用下的翹曲應(yīng)力進(jìn)行仿真計(jì)算，分析了砂漿彈性模量的變化對(duì)框架板溫度效應(yīng)的影響。結(jié)果表明：在溫度荷載作用下，框架板式軌道框架角點(diǎn)處和凸臺(tái)邊緣處將產(chǎn)生局部翹曲應(yīng)力的集中，最大的翹曲應(yīng)力產(chǎn)生在軌道板角點(diǎn)處，并產(chǎn)生最大的翹曲位 |
