Structure assembling by stochastic topology optimization

摘要: Topology optimization is of significant importance to the design truss- and grillage-like structures. Conventional topology procedures are usually based on ground structure approach. Starting from highly connected structures uneconomical links eliminated during course optimization. In this paper we show that, additionally, stochastic methods offer possibility build-up starting simple initial configurations with few elements. Stochastic (simulated annealing, evolutionary algorithms, random cost) applied problem basis appropriate local variations. Results performance comparisons given.
