英文摘要 | The developmental situation of space welding technology at home and abroad is introduced. Then it is put forward that the designing scheme and the computer aided design (CAD) method of main single lens of the domestic space electron beam gun with equal-diameter three-cylinder simple lens, and the flowing-pipe way of calculating the space charge density of the main lens area in the electron gun is analyzed. The parameters calculation of the focusing system is completed through Language C utilizing computer programming and a satisfying result is gotten. The result shows that the calculation and design method are correct: the dispersed focusing current of electron beam is less, the beam section is less in the deflected magnetic field, the minimal radius of beam spot on the workpiece is about 0.656 15mm, and all these can meet the requirements of the space welding and cutting. |
