AI 中文摘要
Michell-Prager型桁架结构由可积离散幂函数与离散对数函数构造而成。研究表明,受合适边界条件约束的特定子晶格可生成近似Michell桁架,这是实现力平衡且节省材料的理论最优结构。通过最小化Michell泛函的形状优化结果,为其最优性提供了数值证据。
英文摘要
The Michell-Prager type truss structures are constructed from the integrable discrete power and logarithmic functions. It is demonstrated that specific sublattices, subject to suitable boundary conditions, yield approximate Michell trusses, which are theoretically optimal structures achieving force equilibrium with material economy. The result of shape optimization minimizing the Michell functional is provided for numerical evidence of their optimality.
