A Model Updating Method for Rocket Based on the Sensitivity Analysis and Optimization Design Technology
Based on the sensitivity analysis and optimization design technology, a new model updating method for rocket is put forward. Firstly, the new method for model updating is presented, and a FEM model for rocket is established subsequently. It is found through mode calculation that the simulation result of the modes is different from the experimental result. Then, the sensitivity analysis model and the optimization design model based on Matlab are established after the parameters to be updated are selected. Finally, the model is updated by the new method. The result suggests that the mode simulation results of the updated model fit well with the experimental value, which validates the model updating method.
