基于随机有限元法的结构柔顺度期望优化设计模型。将基于泰勒展开的随机有限元法引入到拓扑优化柔顺度期望的求解中来(A stochastic finite element method (random finite element method) is used to design the optimal design model of structural flexibility. The stochastic finite element method based on Taylor expansion is introduced to the solution of the flexibility expectation of topological optimization)
