摘要/Abstract

摘要： 大功率质子束加速器广泛应用在基础物理、核工业、家庭安全等领域,其中大功率波导型射频腔极为重要。船形射频腔具有最高的空载Q值和分流阻抗,是GeV质子束加速器的良好选择。船形铜射频腔体的制造,主要难点在于腔体复杂轮廓壳体的成型,为此,本文对其进行了详细的成型工艺研究。通过PAM-STAMP 2G仿真分析软件对高频腔壳体进行了模压成型数值模拟,分别分析了椭圆弧成型过程中壳体的减薄量、残余应力以及成形回弹,为实际模压成型提供了理论依据。根据模拟结果设计的高频腔椭圆壳体成型模具能够成功实现椭圆弧的实际模压成型。

Abstract: The high-power proton beam accelerator is widely used in basic physics, nuclear industry, home safety and other fields, and the high-power waveguide RF cavity is an extremely important component. The ship-shaped RF cavity has the highest no-load Q value and shunt impedance, which is a good choice for GeV proton beam accelerator. For the manufacture of ship-shaped copper RF cavity, the main difficulty lies in the forming of the complex contour shell of the cavity,thus the detailed forming process research is developed in this work. Through the PAM-STAMP 2G simulation software, the die forming numerical simulation for the complex contour shell of the high frequency cavity is carried out, and the thinning amount, residual stress and forming rebound of the shell during the elliptical arc forming process are simulated respectively, which provides a theoretical basis for the actual die forming. The high frequency cavity elliptical shell forming mold designed based on the simulation results has successfully implemented the actual molding of the elliptical arc.

Key words: boat-shaped RF cavity, complex contour shell, die forming, numerical simulation, PAM-STAMP 2G
