| Abstract: | A bus body frame FEM model is built with shell and beam elements,whose accurate is verified by static electrometric tests.The stress,bending moment,torque distribution in static state which has a significant impact on the bus body frame are calculated and the deformation of bus body frame is observed.Also the harmonic response analysis of bus body frame is done to test the dynamic response of mount points and different positions of the floor with the change of the frequency when the engine runs in idle exci... |
