| 4. | The shape optimization of locking hooks is presented by means of stress analysis for six models in the paper 此外本文还对锁闭钩进行了局部应力分析,并对其形状做了改善。 |
| 5. | The stress fields in locking hooks is changed periodically when the train is passing , so the fatigue design criteria are used to check the stress 本文研究了各个载荷工况下,锁闭钩中的最大等效应力与车辆作用载荷变化的关系。 |
| 6. | The model contains nose rail , wing rail , locking hooks and all relative components . the crossties are simplified as elastic foundations . thus , the model reveals the real working state of the locking hooks 论文中采用的计算模型包括心轨、翼轨、锁闭钩等几乎所有的相关部件,没有建模的枕木及地基也做了相应的简化处理,并引入到了边界条件中,比较真实地反映了锁闭钩的真实受力状态。 |
| 7. | A group of calculated results is obtained when the train goes ahead a distance steps . thus , the results in a period are obtained . in addition , the local stress analysis and the shape optimization of locking hooks are done 对于每种载荷情况计算都按照准静态问题进行分析,不考虑结构的加速度,只考虑载荷作用点(火车车轮)的变化,列车每前进一段距离计算一个受力工况,得到一组数据,得到了一个周期的计算结果。 |
| 8. | In this paper a finite element model with several couples of contact surfaces is established to calculate the stress of outside turnout locking device on railway . the effects caused by the deformation of different rails on the stress field in the locking hooks are analyzed by marc software 本文对一种铁路道岔外锁闭装置建立了三维有限元接触计算模型,采用商业软件marc来进行计算,分析了心轨的变形对道岔锁闭钩的受力影响。 |
