The damping of multiple launch rocket system (MLRS) is key parameter of dynamic responses, which influences firing orders and firing interval. For typical structure of MLRS, typical factors of its damping characteristics were analyzed theoretically and the numerical models based on multi-body dynamics method were simulated. The simulation results are consistent with theoretical analysis. The results show that friction in the joint between landing gear and rotary body, erecting cylinder damping and the deformation of flexible bodies are decisive factors of the damping characteristics, while material damping of the metal structure has little effect.
