ABSTRACT

Powered two-wheelers are increasingly adopted for short- and medium-distance urban transport in China; the lightweight open structure demands accurate representation of geometry, mass distribution, connections, and deformation in collision simulations. This study developed and validated a high-fidelity FE model of a powered two-wheeler. A prototype meeting GB 17761-2024 was selected (mass 58 kg, wheelbase 1208.7 mm, height 1058.7 mm, width 387.9 mm, saddle height 808.7 mm). After importing the geometry into ANSA, geometry repair (364 defects corrected), simplification of non-critical components (brake details, wiring harnesses, lamp accessories, support brackets), meshing, connection definition, and material assignment were performed. The final model consisted of 104,217 nodes and 119,567 elements (102,332 quadrilateral shell, 3,183 triangular shell, 14,052 hexahedral solid). Material parameters were assigned based on component functions (frame, tires, pedals, saddle, fenders, battery, lamp cover). To validate the model, a drop-weight impact simulation of the frame and fork assembly was conducted per GB 17761-2024, with a 1 kg rigid roller mounted at the front-wheel position and a 22.5 kg drop weight released from 360 mm. No visible cracks or damage occurred; the wheelbase decreased from 1208.00 to 1202.57 mm (residual deformation 5.43 mm, far below the 40 mm limit). The developed FE model exhibits reasonable geometric accuracy, material definition, connections, and structural response, providing a reliable basis for collision simulation and test-scenario development.
