| 摘要: |
| 陆基车载无人机电磁弹射器是一种新型的弹射起飞装置。为了实现高机动性，提出双边动圈式永磁直流直线电机和定子磁钢轨道分段拼接结构方案。为了评估定子磁钢轨道拼接可能对电机性能的影响，建立了永磁直线电机模型。利用有限元分析软件，分析研究了轨道分段拼接上下错位、左右错位以及倾斜错位可能造成的影响，根据分析结果给出了磁钢轨道拼接错位所允许的偏移范围大小。 |

| Abstract: |
| The land-based vehicle electromagnetic launcher for unmanned aerial vehicle is a new kind of take-off device. In order to realize the high maneuverability, a bilateral moving-coil permanent magnet direct current linear motor with the stator magnet track section splicing structure scheme was presented. In order to evaluate the influence of stator magnet track splice on the performance of the motor, the permanent magnet linear 〖JP2〗motor model was established. The influence of the up and down dislocation, the left and right dislocation and the tilting dislocation of the segmented splice were analyzed by using the finite element analysis software. Based on the analysis, the allowable magnet track splicing offset range was given. |
