In this study, non-linear dynamic FE analysis of a tracked vehicle under the traveling load is
performed by FE code ABAQUS. The stability of vehicle is examined using the structure analysis for
the road wheel. The dynamic analysis is performed by traveling load. The traveling load include the 6
step loading spectrum about road wheel. The stress level around road wheel are 30 MPa ~ 40 MPa.
These value are indicated under modified fatigue strength 50.3 MPa. It takes about 3 second to be
stable the structure after traveling load.
