Abstract:
To provide a theoretical background of vibration problems during missile transportation, the equation of motion of the transportation vehicle and missile are derived by using the energy approach and finite element method, respectively, via the matching of the degrees-of-freedom(DOFs)at the braces between vehicle and missile, the coupled vibration analysis model of the vehicle-missile system is formulated. By solving the coupled vibration differential equation of the vehicle-missile system, the vibration level of the system due to road excitation is analyzed. Numerical simulations are conducted to investigate the influence of different factors, such as the brace stiffness, vehicles velocities, road grades, etc. on the vibration level of a key position on the missile. Results show that the root mean square(RMS)of the dynamic response increases with fluctuations when the vehicles velocity increases, but decreases and tends to be stable with the increase of the bracing stiffness.
