| Abstract: |
| Three-dimensional road surface spectrum model was established based on two-dimensional road surface spectrum model with harmonic wave superposition method. The road surface spectrum was analyzed and its power spectral density was validated. A single-degree-of-freedom tracked vehicle vibration system was constructed. Dynamic simulation on single-degree-of-freedom tracked vehicle vibration system was realized using the three-dimensional road surface spectrum model as virtual excitation input. |
