| Abstract: |
| Objective To analyze the vibration loads of missile transportation and provide input conditions for missile structural reliability analysis and life prediction. Methods According to the dynamical model of missile transporter, the vibration loads under different road surface roughness and velocity were simulated by Matlab/Simulink. The vibration response under different road condition and velocity was obtained. Results The vibration load increased with the decrease of road grade and the increase of transporter speed. Conclusion The time-domain power spectrum density obtained by numerical simulation is consistent with the power spectrum density under standard grade, which can provide input stimulus for vibration response calculation. |
