【Abstract】 Based on the results of experimental modal analysis, a numerical simulation method for dynamic response including stress and displacement of a built up structure is developed. The displacement and stress of a complex structure with unknown parameters under actual operating conditions are calculated and the results are verified by experiment.更多还原
