Many articulated dynamic systems operate in essentially prescribed motion environments. This means that though subsystems are dynamically coupled to the overall system, while the smaller subsystem is significantly affected by the larger system, it has minimal impact upon it. Shipboard systems often fall into this category. Shipboard equipment, aircraft, and personnel are directly affected by the ship motion but do not significantly influence it. The long-term objective of the proposed research is to develop appropriate methodology and computational tools for investigating the complex behaviour of such dynamic systems operating in shipboard motion environments, and using these tools to develop comprehensive understanding of the dynamic interfaces and behaviour of shipboard systems. Short-term objectives involve a combination of refining previously-developed analysis methodologies and expanding them into new areas. Application areas are selected to include rigid multibody dynamic systems where the behaviour of suspension seats on high speed craft will be considered; flexible multibody dynamic systems where maritime helicopter and floating wind turbine transient blade dynamics will be considered; and postural stability of humans where biodynamic models will be developed to assist in predicting the frequency of motion induced interruptions. The proposed research will build on recent advances in the field and achievements within the research group. The approach will remain consistent with recent work and continue to involve theoretical, computational, and experimental components. Fundamental research in this niche area of shipboard dynamic systems is highly topical due to a continuing global trend toward operating shipboard dynamic systems on smaller ships and in increasingly severe sea conditions. It has particular applicability in Canada over the next decade as Canada embarks on the largest shipbuilding program since the end of the Second World War with the design and construction of new frigates, supply ships, patrol boats, and icebreakers. The present research programme will contribute to maximizing operability and safety relating to shipboard personnel and equipment.

许多铰接式动态系统在基本上规定的运动环境中操作。这意味着虽然子系统与整个系统动态耦合，但较小的子系统受到较大系统的显著影响，但它对系统的影响最小。 船上设备，飞机和人员直接受到船舶运动的影响，但不显着影响it. The长期目标的拟议研究是开发适当的方法和计算工具，调查复杂的行为，这样的动态系统在船上运动环境中运行，并使用这些工具来开发全面的了解动态界面和行为的船上系统。 短期目标包括完善以前开发的分析方法并将其扩展到新的领域。 选择的应用领域包括刚性多体动态系统，其中高速船上的悬挂座椅的行为将被考虑;柔性多体动态系统，其中海上直升机和浮动风力涡轮机瞬态叶片动力学将被考虑;和人体姿势稳定性，其中生物动力学模型将被开发，以帮助预测运动引起的中断的频率。 拟议的研究将建立在该领域的最新进展和研究小组的成就之上。 该方法将与最近的工作保持一致，并继续涉及理论，计算和实验组件。 由于在较小的船舶上和日益恶劣的海况下操作舰载动力系统的全球趋势持续，在舰载动力系统的这个利基领域的基础研究是高度热门的。它在未来十年中对加拿大特别适用，因为加拿大开始了自第二次世界大战结束以来最大的造船计划，设计和建造新的护卫舰，补给船，巡逻艇和破冰船。目前的研究方案将有助于最大限度地提高船上人员和设备的可操作性和安全性。
