Mechanical Design and Analysis of LCLS II 2 K Cold Box

[摘要] The mechanical design and analysis of the LCLS II 2 K cold box are presented. Its feature and functionality are discussed. ASME B31.3 was used to design its internal piping, and compliance of the piping code was ensured through flexibility analysis. The 2 K cold box was analyzed using ANSYS 17.2; the requirements of the applicable codes - ASME Section VIII Division 2 and ASCE 7-10 - were satisfied. Seismic load was explicitly considered in both analyses.
