High temperature superconducting (HTS) maglev technology has developed rapidly since it was found possessing the unique characteristics of self-stabilizing suspension. Because HTS maglev needs to work in an external magnetic field environment, it is especially noteworthy to select the appropriate magnetic guideway which is commonly composed of permanent magnets especially for HTS maglev transport applications. With the combination of the conventional single-peak permanent magnetic guideway (PMG) and an individual 'V' shaped support structure, a better 'V' shaped guideway which can generate a higher external magnetic field is obtained. The simulation results indicate that this kind of PMG not only provides the HTS maglev with sufficient suspension performance, but also better guidance capability at the same time. With regard to the typical work condition (the 30 mm field cooling height, the 10 mm work height and the 10 mm lateral displacement), the levitation force and guidance force can be achieved to 6778 N/m and 2778 N/m, respectively. The study is referential to the magnet guideway optimization for the engineering application of HTS maglev.
