项目摘要

The research project aims to improve the safety of ships with a double hull construction by filling them with a suitable granular material. This involves developing and validating simulation methods to increase the collision safety of double-hull vessels. For this purpose, granular materials are used to fill the cavity between the two hull layers which can also be emptied for inspection purposes. In the event that a double hulled-ship collides with another vessel, the use of the filler material increases the penetration resistance, so that a penetration -- of the counterpart's bulbous bows, for instance -- can be avoided. This would considerably reduce the risks of a collision. To evaluate the effectiveness of various granular filling materials, a multiscale simulation method combining modern particle methods and finite element methods is being developed. It will be used to simulate a collision event and examine the suitability of different granular fillers. In the proposed second period of this project the simulation methods will be further developed and applied to the computation of a real double hull structure of a vessel. This will enable us to assess the room for improvement of double hulls that are are filled with granular material. Appropriate experiments will be designed to validate the simulation and to enable a parameter identification of the material models used during the finite element analysis.

该研究项目旨在通过填充合适的颗粒材料，通过双船体结构来提高船舶的安全性。这涉及开发和验证模拟方法，以提高双壳血管的碰撞安全性。为此，使用颗粒材料来填充两个船体层之间的腔，也可以清空以进行检查。如果双船只船与另一个容器相撞，则使用填充物材料会增加渗透性耐药性，因此可以避免渗透（例如，对应物的球茎弓）的穿透性。这将大大降低碰撞的风险。为了评估各种颗粒状填充材料的有效性，正在开发一种将现代粒子方法和有限元方法结合的多尺度模拟方法。它将用于模拟碰撞事件并检查不同颗粒填充剂的适用性。在该项目的拟议的第二阶段中，将进一步开发仿真方法，并应用于容器的真实双壳结构的计算。这将使我们能够评估改善装有颗粒材料的双壳的空间。将设计适当的实验，以验证模拟并启用有限元分析过程中使用的材料模型的参数识别。
