Abstract: The chassis frame of a heavy
lectra haul is analysed by both modal experiment method and
finite element method (FEM). The first ten order modal
parameters of the chassis frame have been obtained
satisfactorily. These parameters have important reference value
in designing the chassis frame properly and provide a necessary
basis for the fault diagnostics of the truck.
