So in order to analysis the impact of different alignment on the comfort index, we should establish a dynamic model to make a car-guideway coupling emulation.

因此，为了分析不同线路设计参数对舒适度的影响，应采用车—线耦合动力学模型进行计算仿真。

Coupling is a coupling of locomotive and car parts, commonly used have a link bolt and rotary chain, large car adopts automatic coupling with both buffer action.

联接器是联接机车和矿车的部件，常用的有插销链环和回转链，大型矿车采用兼具缓冲器作用的自动车钩。
