In order to improve the operational efficiency of suspended intelligent monorail trains, a whale is used as a biomimetic object to design the appearance of the train and study its aerodynamic performance. Innovatively design the head shape of a suspended intelligent monorail train using whale bionics. According to the special morphology of different whale parts, the upper surface, side surface, and lower surface of the train were designed separately. The aerodynamic performance of the three innovative design trains was analyzed through turbulence models. Under exponential wind load, the air resistance of the train after innovative design was significantly reduced, with the highest resistance being around 3500 N. At different wind speeds and wind direction angles, the overturning moment and lateral force of the train were lower than the corresponding limit values, ensuring the stability and safety of train operation. Compared to traditional models, the design of whale like trains has lower resistance and higher operating efficiency. Its form design and aerodynamic performance research have certain value and significance for the development of suspended intelligent monorail trains.
