某結構在振動-加速度復合環(huán)境下的響應優(yōu)化

Optimization of structure response under vibrafuge environment

摘要: 文章以結構的安裝角為設計變量，根據(jù)結構安裝位置的合理性來確定設計變量的約束條件。以結構關鍵部位的加速度均方根值作為目標函數(shù)，建立了隨機振動-加速度復合載荷作用下基于安裝角的某結構響應優(yōu)化模型。應用ANSYS軟件中的參數(shù)化設計語言（APDL）實現(xiàn)了離心場中結構隨機振動響應對安裝角度的靈敏度分析及優(yōu)化。優(yōu)化后的結構振動響應降低了。

Abstract: An optimized model of a structure under vibrafuge environment is built with the fix angle as the design variable. At the same time, the rationality of the fix position is used as the restrictive condition and the RMS value of the acceleration at key points is used as the objective function. The parameter design language (APDL) of ANSYS is applied to perform the sensitivity analysis and the optimization of the structural vibration response under the centrifuge field. The vibration response is obtained after the optimization.
