摘要
将结构分析中的最小总势能原理加以推广,建立了结构优化中的最小总势能模型,使结构的分析与优化相结合,不再需要在每次迭代中进行完整的重分析。这种方法充分利用了结构优化的并行性;算例表明,其具有较高的加速比和计算效率。
This paper presents a structural optimization medel based on minimizing the totalpotential energy, thus giving an integrated iterative scheme in which both structural equilibriumand optimization are reached within a single cycle. The structural reanalysis is not required at allin the proposed method. This method can explore fully the inherent concurrency and parallelismin the structural optimization problem, so it is very suitable for parallel computing. Thenumerical examples have demonstrated the high speedup and efficiency of this method.
