【Abstract】 Nonstationary random vibration of linear vehicle systems with variable driving speed on rough ground road are studied in this paper. Both in time/space domain and frequency domain, the analytical solutions of the probablistic characteristics of the nonstatlonary random vibration of the vehicles traveling straight on rough road with uniformlyvariable speed are derived by means of mode-superposition method.The procedure can be used in dynamic design of vehicles and road surface spectrum study.更多还原
