Abstract

Combined with the actual working environment, building chassis frame of the entity model by the Solid works software for FB45 hydraulic truck. The analysis software ANSYS is used to calculate the prestressed modal analysis and random vibration analysis(PSD), acquired the random vibration simulation results when the truck driving in dangerous conditions. These results could provide some useful suggestions for design and improvement for the truck’structure and to avoid resonance.
