With the increasing demand for Urban Air Mobility (UAM), personal ground-operable air mobility systems capable of ground operation and vertical flight are emerging as next-generation mobility platforms. However, the lack of structural design criteria for such dual-mode systems makes it difficult to achieve both structural safety and weight efficiency. In this study, a truss-structured personal air mobility frame using Al 6082-T6 aluminum alloy was designed based on structural requirements derived from the KSAE Baja competition. Dynamic finite element analysis was performed using Abaqus/Explicit under displacement-controlled loading conditions. Two pipe thickness models (3.0T and 2.0T) were compared to evaluate the effect of weightreduction design on structural behavior. The results showed that the 2.0T model achieved a 31% weight reduction (from 15.1 kg to 10.4 kg) while maintaining stable structural behavior and energy responses. Stable dynamic structural responses without numerical instability were confirmed through energy balance evaluation. These findings demonstrate the feasibility of lightweight personal air mobility frame design.
