基于ANSYS技术的双轴对称工字型截面梁优化设计

OPTIMIZATION DESIGN OF I-TWIN AXIS SYMMETRICAL BEAM BASED ON ANSYS

双轴对称工形截面钢梁在土木工程中有着广泛的应用,对这种受弯构件的设计目前采用的是试算法,在进行结构设计时,往往需要进行大量的计算工作。根据优化设计原理给出梁优化设计的数学模型,利用通用有限元计算软件ANSYS对某平台梁进行优化实例分析,得出优化结果,并根据优化结果提出构件设计的建议。

The beam with twin axis symmetrical I-section is used widely in civil engineering, the design of the component of steel structure is made by trial and error, lots of calculations must be done when the design of structure is made. It is built a mathematical model of optimization design of I-beam, and analyzed an example of I-beam using ANSYS. The result of optimization is got, and it is put forward some advices of the design of a beam with twin axis symmetrical I-section.
