如图1所示，本实施例提供了一种真空管道高温超导磁悬浮高速试验平台。
参见图1，图中示出了本申请中包括真空管道15(图中未示出完整的管体)、支撑平台、模型车1和龙门架8。其中，其中需要说明的是：在本申请中还包括与真空管道15配合使用的真空系统(图中未示出)，其中真空系统具体结构可以是现有技术中分子泵与机械泵的结合抽取真空的方式，本申请中不再赘述。具体而言，在本申请中，真空管道15一端为封闭，真空管道15的另一端设有真空隔离门(图中未示出)，通过控制真空隔离门的开启与关闭实现模型车1的检查与维护。进一步地，在本申请中，支撑平台设置于真空管道15内，支撑平台上设有永磁轨道7和定子绕组13，需要说明的是，在本申请中定子绕组13包括定子铁芯和与供能设备电连接的线圈，模型车1的底部设有动子3和低温杜瓦5，还需要说明的是，在本申请中动子3也和供能设备电连接，其中，低温杜瓦5固定连接在位于模型车1的转向架上，低温杜瓦5内设有超导块材，定子绕组13与动子3通电后耦合产生驱动力构成电励磁直线同步驱动系统，推动模型车1前进，超导块材与永磁轨道7配合产生悬浮力，模型车1的侧壁由金属材料制成；龙门架8设于支撑平台上，龙门架8的立柱上设有永磁体9，永磁体9与模型车1的车体耦合，在模型车1的车体上形成涡流。具体而言，龙门架8、永磁体9和支撑平台围合形成的空腔供模型车1穿过，进一步而言，在本申请中，永磁体在模型车1侧壁的投影面积占模型车1侧壁的30％以上，换而言之，永磁体在模型车1侧壁的投影面积占模型车1侧壁面积的百分比大于等于30％。在本申请中，通过真空管道15用于提供高温超导磁悬浮列车的低真空环境，以减小列车运行过程中的阻力，同时提高磁悬浮系统的悬浮性能，使科研人员研究时速400km及以上时的高温超导磁悬浮悬浮和导向性能；并且由于真空管道15减少了外界空气的干扰因素，在本申请中可以较为纯粹的研究高温超导磁浮车-轨耦合作用机制及动态稳定 性。然后，进一步地，通过控制真空度还可以探究高温超导磁悬浮车轨间磁-电-力-气多物理场动态耦合机理以及低气压环境下高温超导磁悬浮车的悬浮、导向、气动特性研究。并且进一步地，由于在本申请中龙门架8上的永磁体9与模型车1侧壁构成的涡流制动制动系统，其由于能产生更大的制动效果，相比于现有技术，其制动距离更短，并且能有效的利用现有的模型车1结构，无需进一步地定制涡流制动所需的转向架，降低本申请中定制成本。同时，在本申请中，将永磁体9直接固定在龙门架8的立柱上方式，可以有效的根据模型车1最终试验的速度进行永磁体9的磁通量控制，可以有效地在400km/h的速度之上对模型车1进行制动，确保整个实验装置的安全性。
进一步地，在本申请中进一步地将真空管道15内分为三个区域，第一个为电机加速段18、第二个为电机减速段19以及第三个为涡流制动段20，通过上述对真空管道15内区域进行划分，可以有效规划实验进程。
进一步地，在本申请中，为了实现400km/h的模型车1速度，在本申请中，定子绕组13为两组，支撑平台包括支撑结构11、承载平台12和定子安装架16，支撑结构11固定于真空管道15底部，承载平台12水平设置于支撑结构11上，定子安装架16为U型设置,定子安装架16的水平部与承载平台12固定连接，两组定子绕组13分别设置于定子安装架16的内侧壁上，动子3设置于两组定子绕组13之间，通过上述方式，采用在两侧的定子绕组13同时通电的方式，位于中部的定子受到更多的交替的斥力和吸力。并且为了平衡水平方向的受力，在本申请中动子3设置于定子安装架16的对称轴上，同时，在本申请中，定子绕组13在竖直方向上的长度大于模型车1的宽度。上述的设置方式，能为定子绕组13和动子3在竖直方向上提供大的重合面积，为动子3提供更大的速度。并且，进一步地，为了 获取模型车1的相关运行数据，在本实施例中，在定子安装架16上设置位置检测装置(图中未示出)，具体设置位置位于定子安装架16竖直部分上。其安装与定子绕组13上方或下方均可，本申请中不做出具体的限制。具体而言，位置检测装置可以为激光测距仪，然后进一步地，在动子3对应的高度上设有按照预设规律排布的凸起，排除高速带来的影响。比如，在申请中采用间距均不相同的方式排列第一组凸起，用间距均相同的方式排列第二组凸起，用间距均不相同的方式排列第三组凸起，其中第一组所采用的间距均小于第三组所采用的间距。通过上述的实施过程中，在检测距离信号中，会首先出现第一组突起带来的周期不相同距离变化，第二组较为稳定周期的距离变化，最后出现周期不相同距离变化，且最后出现的距离变化周期大于第一次，依次排除高速运行中设备的设备误差，间接定位在整个试验过程中的模型车1运动情况。同时，在本申请中定子安装架16内面侧的底部开设有V型槽10，动子3靠近定子安装架16底部的一段为与V型槽10相匹配的V字型设置，动子3的V字型的一段延伸至V型槽10内，V型槽10的对称轴与定子安装架16的对称轴重合。在本申请中通过在动子3下的V型槽10的抑制直线电机的法向力，在模型车1运动过程中，定子产生的行波磁场除了能够产生沿运动方向的驱动力之外，还会产生垂直与运动方向的法向力，若没有V型槽10的约束，那么动子3就会与侧面相撞，在本申请中通过增加V型槽10防止侧面发生撞击。
进一步地，在本申请中支撑平台还包括基座4，基座4设置于定子安装架16顶部，并盖合定子安装架16，基座4上开设供动子3穿过的移动口，移动口的对称轴与定子安装架16的对称轴重合，永磁轨道7的两条永磁轨分别设置于移动口的两侧，并与移动口平行设置。 同时了进一步降低本申请中其他零部件对永磁轨道7产生的磁场影响，在本申请中，基座4由不锈钢材料制备而成。而永磁轨道7与基座4之间还设有隔磁基座，隔磁基座与永磁轨道7以及隔磁基座通过螺栓链接，永磁轨道通过螺栓固定在不锈钢的基座4上。
并且，在本申请中为了进一步保障模型车1的安全，尽快地使得模型车1在400km/h以上的速度降低到零，本申请中优选永磁体9为条状设置，永磁体的长度大于模型车1的长度。具体而言，在本申请中永磁体9可以是由多个小永磁体9单元拼接而成，本申请中不做出具体限制。同时，为了平衡模型车1左右两侧的受力，在本申请中永磁体9的数量为两条，两条永磁体9分别设置与龙门架8的两内侧上。

以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
以上，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
