Using a computer program for the evaluating of free eligible rotation-symmetrical cylinder shells the number of magnitude of the natural-frequencies were estimated. Assuming the skull of being annulary fixed the calculated values doe in the same range as those got from deat bodies or macerated skulls respectively. Modeling the vibration conditions for the non-fixed border of the skull, the mode shifts into a singulaer point on the rotations axis. In fact the mode in exactly known basis fractures tends to go to the vertex.
使用计算机程序评估自由合格的旋转对称圆柱壳，估算了固有频率的数量级。假设颅骨为环形固定，计算值与分别从尸体或浸软颅骨获得的值在同一范围内。对颅骨非固定边界的振动条件进行建模时，模态会移动到旋转轴上的一个奇点。实际上，在确切已知的基础骨折中，模态倾向于趋向顶点。
