摘要
基于极大熵原理，提出了一种新的杆系结构拓扑优化方法．通过引入应变能密度函数，将极大熵与拓扑优化建立了内在联系，从而将拓扑优化问题转化为寻求最佳应变能分布的问题．最后给出了几个典型算例，结果表明，结构的刚。
A new method of topological optimization is presented for truss structures based on the maximum entropy principle(MEP). In the method, the coherent relationship between MEP and topological optimization is established by introducing the function of energy density so that the problem of searching the optimum topological form is transformed into the problem of finding the optimum distribution of the energy. Several computed examples are given and the results show that the reliability of the structural stiffness and strength increases with the increasement of the information entropy.
