Design and Manufacture of Special-shaped Section Expansion Joint for Vacuum Pipe of High-speed Flying Vehicle
The full name of high-speed flying car is ultra-high-speed low vacuum tube maglev transportation system.In or-der to develop a special-shaped section expansion joint that meets the requirements of the high-speed vehicle vacuum pipeline sys-tem,innovative calculation methods and structural design were adopted,and tests were conducted on the exemplar.Through test verification,the results verifies that the design parameters of the expansion joint,including its sealing properties,and fatigue life,meet the technical specifications.The successful development of the special-shaped section expansion joint solves the con-nection and flexibility issues of the vacuum tube for high-speed vehicles,ensuring the steady progress of the overall high-speed vehicle project.
