真空管道运输在未来物流体系中的角色与定位

Role and Position of Evacuated Tube Transportation in the Future Logistics System

就真空管道运输实现以后,在未来物流体系中扮演的角色、定位,真空管道物流运输的特点、基本模式,真空管道货运车厢的设计与运行方式等进行讨论。研究认为:(1)真空管道运输将跟现有的水运、铁路、公路、航空运输业形成竞争,分流一定的货源;(2)真空管道运输是对现有运输方式的补充,虽然在部分功能上会发生替代,但是,真空管道运输不会取代铁路、公路、航空等运输方式;(3)真空管道货运车厢均须为全密封的,但不需要安装生命保障系统;(4)真空管道冷藏车厢的制冷系统在行驶过程中不允许跟管道真空环境进行气体交换,但真空环境是良好的绝热介质,在真空管道中运行的冷藏车厢恒温条件容易得到保证;(5)在规划设计真空管道运输系统时应考虑设置真空管道货运站。

This paper discusses the role and position that evacuated tube transportation（ETT）will play in the future logistics system after ETT is achieved,features and basic model or ETT logistics,and designing and operation of ETT cargo carriage.Some results have been set up：（1）ETT will compete with current marine,railway,highway and aviation,sharing some supply of goods.（2）ETT will be a makeup for current transport modes,although replacing some functions of current transport modes but wouldn＇t replace them completely.（3）ETT cargo carriage must be hermetic and airtight,but needn＇t a life support system.（4）Refrigeration system of ETT refrigerator car will be prohibited to exchange gas from vacuum circumstance into carriage,but luckily,vacuum circumstance is favorable heat insulation medium so that it would be easy to keep a constant temperature in it in operation.（5）ETT freight docks should be considered when planning ETT system.
