Lightweight materials such as high-strength steel, aluminum alloy or magnesium alloy applied as substitutions of plain steel to manufacture of bearing structures on vehicle have been an obvious tendency. Using industrial aluminum alloy as material, a new light bus frame was designed in this paper, and then finite element simulations under multiple typical conditions were implemented based on the reasonable finite element model. First, all the components of the frame were designed, assembled and checked in CATIA. Secondly, the frame-suspension finite element model was established in ANSYS Workbench after model simplification, connections simulation, etc. Finally, finite element simulations under totally five kinds of typical conditions such as full-load bending and emergency braking were accomplished, and the results indicate that the strength and stiffness of this new bus frame can satisfy the requirements of the typical conditions.
