In the analysis, firstly, the flux boundary condition is used to simulate the frictional heat resource between wheel and rail. The non-steady heat transfer between the contacting surfaces of the wheel/rail, heat-convection and radiation between the wheel/rail and the ambient were all taken into consideration. Therefore, a heat coupling model of the wheel/rail in rolling/sliding is put forward to calculate the frictional temperature rise in the wheel and rail. Secondly, after the temperature distribution of wheel/rail, due to friction, is calculated, substitute the thermal load with equivalent fictitious body force and boundary distributed force loaded on the nodes of the corresponding elements. The wheel-load is applied to the center of the wheel.
首先,用热流边界条件模拟轮轨接触界面的摩擦热源,考虑轮轨间的非稳态热传导、轮轨自由表面与环境的热对流、热辐射的影响,建立轮轨滚动接触热耦合有限元计算模型,分析计算轮轨滚、滑工况下的摩擦温升;其次,以求得的轮轨温度场结果作为求解轮轨应力场的已知条件,轮载以集中力形式直接加载于轮心处,将摩擦温升引起的热载荷等效为假想体力和热边界面力,施加于相应的单元节点上,建立了轮轨热—机械载荷耦合作用的热弹性平面应力模型,分析热—机械载荷作用下的轮轨应力场。

In addition, total wheel/rail contact calculation with divided rail outline method are raised. Under the condition of considering the displacement, bouncing, yaw, roll of wheelsets and displacement, bouncing, roll of rails, minimum gap between rail and wheel were calculated by the trochoid method and divided rail outline method, we can easily judge totally real contact states of the wheel/rail such as normal one-point contact, nonnormal one-point contact, two-point contact and wheel complete lift. Wheel/rail normal forces in the two contact point are respectively calculated by nonlinear Hertz contact theory, and then, result of simulation more close to reality on actual track.
另外,提出了轨廓分区法全面计算轮轨接触状态法,在考虑轮对的横移、浮沉、摇头、侧滚和左右钢轨的横移、浮沉、侧滚的条件下,可全面地分别计算左右侧轨顶和轨侧区域与车轮的最小轮轨间隙量,以此来判断轮轨的真实接触状态:正常的一点接触、非正常的一点接触、两点接触和车轮完全悬浮,并根据非线性赫兹接触理论分别求得两接触点处的轮轨法向力,从而使仿真结果更接近于车辆在实际线路上的运行状态。

The ratio of the vertical load distributed between the arch rib and the tie beam of the two schemes is the same. For the integral girder deck scheme, the longitudinal beams and the deck slab of endure more axial force compared to the ballast girder deck scheme, especially to the deck slab with a conspicuous increase of the axial force and higher stress, and the tie beam endure less. The force-bearing characteristics of the cross beams under the integral girder deck scheme is obviously better than that of the ballast girder deck scheme, especially at the two ends of each cross beam.
在受力上,与道碴板桥面方案相比,整体桥面方案竖向荷载在拱肋和系梁之间的分配基本相同,混凝土板和纵梁分担的纵向力则相对更大,尤其是混凝土板,增幅较明显,应力水平整体较高,系梁分担的纵向力则得到减小,横梁的受力状况整体桥面方案明显优于道碴板桥面方案,特别是在梁端处。

Look at this girder again, the ornament of the line was Exquisite, it was different from the girder which was in the Cosco.(maybe I didn't see much of the girder in the Cosco. Who think that belongs to the Cosco can show the picture to us.) on seeing this style of this girder, I recognized the saddle iron in Sichuan. Consequently, I don't think it is from the Tibet
再看这个提炼,龙头纹饰刻画得相当精美,纹饰和和常见的中原明清刀提梁相似却并不相同(当然,也许我中原地区提梁也见得不多,哪位觉得这是中原的,不妨贴个纹饰相同的出来看看),看这个提梁的纹饰风格,我不禁想起了这回入川看见的藏族用雕龙头的铁马镫,个人以往风格非常接近,因此,我认为这还是藏区的。
