基于Lingo的离散型桁架结构全局拓扑优化设计

Lingo is used to solve global topological optimal design of discrete-sizing trusses problem. A brief introduction about Lingo is first proposed. Then, a modified mathematical model is detailed regarding some constraints including stress, stability, and displacement, under multiple loading conditions. In addition, multiple analysis of a truss technology is assigned in order to reduce the calculation workload. Ultimately, in order to examine the practicability of the approach and the model, a well-studied truss structure example is used to demonstrate the feasibility and effectiveness of such method and approach, which successfully reflects that the usage of Lingo to optimize trusses is an effective method.
