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。
In order to achieve the precise control of the pressure and deformation of the shell during the cold-spring assembly of the helical TWT slow-wave assembly, a new type of clamping scheme is proposed. The deformation, stress and strain of the shell during the press- Were studied. According to the technical characteristics of the assembly process of the existing slow wave components, based on the connection conditions between the jaws and the pressing bars, the influence of the clearance of the movement pair on the precise control of the deformation of the shell is analyzed. A precision holding method of the posture determination is proposed. Through the establishment of the shell of the equivalent force model, the shell deformation calculation and stress analysis. The results show that within the range of linear elasticity, the displacement of the total displacement of the shell at the force application point is 0.62%, and the stress deviation is 9.8%. It can be seen that the result is highly effective. The development of new components of the slow wave precision press equipment has a certain application value.
