| Abstract: |
| In structural topology optimization,variable connection means that topology variables are connected with constrains in order to obtain specific configuration,and to meet the requirements of engineering design and restrictions of manufacturing technology.The formula with variable connection concept for several filtration methods and sensitivity analysis is presented.Meanwhile based on the software integration platform SiPESC and topology optimization software SiPESC.TOPO,a new algorithm design framework for variable connection concept of topology optimization is constructed.The core idea of software design is that algorithmic class and data model class are designed individually using object oriented methods and software design patterns.The mechanism of variable connection and the interfaces of software modules are discussed in detail.Finally,the feasibility of variable connection concept and algorithm framework on static problems,dynamic problems and heat conduction problems were verified by numerical examples. |
