And use this optimization program computate the boom structure shape of heavy bucket - wheel stacker & reclaimer ; based on shape optimization , we use second optimization technology to optimize structure section size . the optimization results are satisfied . the computation indicates that considering the geometric nonlinear element can enhance the calculation efficiency and precision of optimization design evidently in sensitivity analysis 編制了空間剛架結(jié)構(gòu)優(yōu)化設計程序( 3dfem - opt . for ) ,并利用編制的優(yōu)化程序?qū)δ炒笮投份喍?取料機前臂架在最大應力約束條件下,進行結(jié)構(gòu)形狀優(yōu)化設計;在形狀優(yōu)化的基礎上,采用二次優(yōu)化技術,對結(jié)構(gòu)的截面尺寸進行了優(yōu)化。
The paper analyses the characteristic of the self - vibration , the influence on the whole structure stiffness and the vibration shapes from the variation of the floor - slab section , the variation of the primary structure section , the variation of the secondary structure section , the variation of the shear wall section , explaining the method of the sub - structure ( which is the super - element method ) , which is effective 本文通過多種計算模式對雙塔結(jié)構(gòu)的自振特性做了研究,分析了主、次框架截面、樓板截面和剪力墻截面變化后對結(jié)構(gòu)整體剛度的影響,同時說明了子結(jié)構(gòu)(即超單元)方法對求解此類結(jié)構(gòu)的有效性。
