摘　　要：为了实现对螺旋线行波管慢波组件冷弹压装配过程管壳压力和变形量的精密控制,提出了一种新型夹持方案,并对管壳在压装过程中的变形量、应力应变情况进行了研究。根据现有慢波组件装配过程的工艺特点,基于卡爪与压条间的连接条件,分析运动副间隙对管壳变形量精密控制的影响,提出一种姿态确定的精密夹持方法。通过建立管壳的等效受力模型,进行了管壳的变形计算和应力的分析。结果表明,在线弹性范围内,管壳在力作用点处总变形量位移的偏差为0.62%,应力的偏差为9.8%,可知结果具有较高的有效性。对开发新型慢波组件精密压装设备具有一定的应用价值。A novel assembly technique of the helix slow wave structure（ SWS） withtube housing was developed to precisely control the force and deformation. The dependence of thedeformation on the joint clearancein the proposed clamping scheme was investigated. The impact of the load on the deformation and stress distribution of the tube housing assembled in the newly-developed technique was mathematically modeled,theoretically analyzed in Castigliano＇s method,and numerically simulated in finite element method with software ANSYS. The simulated results show that in the elastic deformation range,the relative discrepancies of the stress and total deformation,at the spots exerted by external forces,are below 9. 8% and 0. 62%,respectively. We suggest that the new assembly technique of tube housing be of some technological interest in development of the precision assembling equipment for helix SWS.
