【Abstract】 Structure dynamic design is very important to improving the flexible structure’s reliability in aircraft or ship engineering. The creation of parametrical finite element model for the flexible structure is discussed, and the dynamic performance sensitivity analysis and intelligent design for the structure are also presented in this paper. The application of ANSYS Parametrical Design language (APDL) and back propagation (B-P) neural network in the flexible structure dynamic design is also studied.更多还原
