1) additional draft
附加牵伸
3) draft zone with a twister
加捻牵伸
6) additional contractility
伸缩附加力
1.
That was found after studying the interaction behavior between the railway bridge and CWR and the distribution rule of additional contractility.
通过对梁轨相互作用原理及伸缩附加力分布规律的研究,考虑连续梁中部存在一段梁轨位移相等点的情况,建立新的伸缩附加力计算模型,并用Levenberg-Marquardt算法进行求解、分析。
2.
Compare d with the conventional method, LM can overcome the accumulative errors,s o in the calculating of the additional contractility of BCWR (bridge continous w elded rail),LM method can be used on multi-span bridges, especially .
在现场超多跨梁,特别是城轨高架桥的无缝线路伸缩附加力计算中,推荐采用LM算法。
