Shield tunneling machine cutterhead structure variation reconstruction method based on vibration energy analysis

A shield tunneling machine cutterhead structure variation reconstruction method based on vibration energy analysis comprises the steps that firstly, a design object is defined, design variables are defined, and reinforcing ribs are geometrically described in an explicit mode; performing energy finite element calculation and iterative optimization; and finally carrying out adaptive processing. According to the method, an explicit topological optimization method is used as a basic tool to drive variation and reconstruction of a shield tunneling machine cutterhead bearing framework, an energy finite element analysis method is combined, vibration energy dissipation of the shield tunneling machine cutterhead is guided and strengthened, suppression of structure dynamic response is achieved, the calculation pressure is greatly reduced, the calculation precision is high, and the calculation amount is small. 一种基于振动能量分析的盾构机刀盘结构变异重构方法，先定义设计对象，定义设计变量，显式几何描述加强筋；再进行能量有限元计算，迭代优化；最后进行适应性处理；本发明以显式拓扑优化方法为基本工具，驱动盾构机刀盘承载架构的变异与重构
