摘　　要：针对常规慢波组件管壳冷挤压过程中,压力和变形量难以精确测量的问题,提出了一种新型慢波组件冷挤压装置。采用三个长度略大于管壳的压爪周向均布,应用伺服电机自动加载控制压爪进给量,使用压力传感器和位移传感器实时监控测量挤压过程中滑套推力与管壳形变。对其传动过程进行了分析计算,得到滑套受推力与管壳形变之间的理论关系,并进行有限元仿真与冷挤压实验研究,三者结果一致性较高,可知该方案具有一定的实际应用价值。Here,we addressed the difficulties of precision measurement of pressure and deformation in assembly of tube and slow wave structure（ SWS） by cold extrusion. The solution was the modified cold extrusion setup,mainly comprising three claw-clamps,a little longer than the tube and evenly installed at 120 o around the tube,a servo-motor,pressure/displacement sensors,host computer and high precision automatic control unit. The servo motor automatically feeds and precisely loads the claw-clamps; the sensors combined with the control unit realize the accurate measurement,real-time monitoring and precise adjustment of the pressure and tube deformation. Moreover,the assembly of the tube and SWS with the novel setup was mathematically modeled,theoretically calculated,numerically simulated and experimentally evaluated. The simulated,calculated and measured results were in good agreement. We suggest that the newly-developed set-up be of much technological interest in assembly of the tube and SWS
