The superconducting magnetic levitation (Maglev) systems for trains running at higher speeds than the Shinkansen trains, which represent the high-speed railway in Japan, have been developed. In order to achieve the levitation running, the reduction in weight for the Maglev vehicles is required, and therefore aluminum alloys are applied to bogie frames, while steels are still used for the conventional railway. Considering that the strength of aluminum alloys is relatively low, the safety and reliability method for designing the bogie frames made of aluminum alloys was newly introduced, fulfilling the requirements for the application, such as load conditions and strength conditions. From the results of bench tests, including metal fatigue tests, after trial manufacture and running tests in Yamanashi Maglev Test Line, it was verified that the new design method based on quality control was established.
