提出了一种新的拓扑形状优化方法。其基本思想是将新孔（所谓的“气泡”）迭代定位到组件的当前结构中。因此，这个概念被称为“气泡法”。新气泡的迭代定位通过不同的方法进行，其中包括通过求解变分问题。新气泡的插入导致拓扑类的改变。对于这些不同类别的拓扑结构，分层结构的形状优化，确定当前气泡的最佳形状，以及其他变量的边界，进行。
This paper addresses a novel method of topology and shape optimization. The basic idea is the iterative positioning of new holes (so-called ''bubbles'') into the present structure of the component. This concept is therefore called the ''bubble method''. The iterative positioning of new bubbles is carried out by means of different methods, among others by solving a variational problem. The insertion of a new bubble leads to a change of the class of topology. For these different classes of topology, hierarchically structured shape optimizations that determine the optimal shape of the current bubble, as well as the other variable boundaries, are carried out.
