高温超导磁悬浮车导向力测试装置

An equipment measuring guidance force of a HTS Maglev vehicle

介绍了一套基于高温超导磁悬浮实验车的整车导向力测试装置。该装置由两套推进系统和两套力传感器组成,传感器固定在车上。每套推进系统可在水平和垂直两个方向运动,可完成实验车在不同悬浮高度的横向导向力测试。两套推进系统通过链条齿轮连接,同步精度0.5mm,水平运动范围0～20cm,水平位移精度1mm;垂向运动范围0～10cm,垂直位移精度1mm。利用该装置测量了整车在不同悬浮高度的导向力,并初步研究了整车导向力与悬浮高度及横向位移的关系。

An equipment measuring guidance force of a high temperature superconducting （HTS）Maglev test vehicle is reported. It includes two sets of propulsion systems and two sets of force sensors. Each propulsion system can move in horizontal direction and in vertical direction so that it can measure guidance force of the whole test vehicle at different levitation gaps. Force sensors are fixed on the vehicle. Two sets of propulsion systems are connected by a chain, synchronization precision: 0.5 mm, moving range in horizontal direction: 0～20 cm, horizontal moving precision: 1mm; moving range in vertical direction: 0～10 cm, vertical moving precision: 1 mm. Experiments prove that the equipment can measure the guidance force of the whole test vehicle successfully and guidance forces of the whole vehicle at different levitation gaps are measured. Relation between guidance force and levitation gap and lateral displacement is studied preliminarily.
