  • Recently, in the stage of early planning and concept design for ships and other large structures, the designer must take into account the shortest term, highest accuracy, lowest cost and best efficiency when selecting a plan from among many structural models. In this stage, it is not always easy to make designs using large structural analysis by FEM. Our studies focus on the structural analysis with optimal accuracy and efficiency needed in the early-stage design of frame structures and thin-walled structures, and on the practical application system of structural analysis implementing new concepts.

  • Research
  • Recently, the reduction in size and weight of machine products is given as one approach of the industrial world to energy problems. However, the vibration and noise problem at high frequency shows a tendency to occur because of the thin plate structure. The following contents are examined using energy analysis methods.
    i) Identification of vibration source and noise source
    ii) Reduction of vibration and noise
    iii) Expansion to diagnostic technology as to vibration and noise

  • Ship and Ocean Hydrodynamics
  • Research
  • In order to plan and design various kinds of offshore structures, it is necessary to analyze and evaluate the hydrodynamic performance of those offshore structures. We study a method to predict, theoretically and experimentally, the response character- istics of offshore structures with reference to the effect of mooring system in waves.
    Moreover, a new type of offshore structure with excellent performance is investigated by use of the above method, and its potential for realization is evaluated.

  • Ocean Renewable Energy Utilization Marine Hydrodynamics
  • Research
  • Promotion of ocean renewable energy is one of the main energy resources for the future from the view-point of global warming and national security of energy resources. Political issues by the government, strategic arrangement of infrastructures and supply chain by industries and additional schemes to catch up to front runners such as Europe are studied.Motion of floating bodies and marine hydrodynamics are also studied.

  • Ship Hydrodynamics
  • Research
  • Ships have to move a large volume of cargo to desired destinations cheaply and on time. In order to achieve projected objectives, the target speed has to be attained by smaller engines.
    Put another way, the improvement of propulsive performance is desired.
    We study low-resistance ship forms and high performance propellers theoretically and experimentally.
    Experiments are conducted in the towing tank (L×B×D=60m ×4m×2.3m) and the small circulating channel at NIAS.

  • Research
  • In recent years disasters due to earthquakes or strong winds have occurred frequently. In order to construct buildings safe and secure in earthquakes and wind, studies are conducted on design methods that evaluate dynamic behaviour and elasto- plastic behaviour appropriately.

  • Research
  • A calculating program is developed to analyze the unsteady hydrodynamic forces acting on a 2D oscillating wing which advances below a free surface.Then, free surface effects are computed by constructing the unsteady Green function considering wave generation caused by 2D vortex.

  • Hull Structure Analysis Ship Design System
  • Research
  • Recently, with the development of computers, it is necessary to use CAE and CAD for efficient design of large structures such as ships and offshore structures.So our studies focus on the design of the hull structure, which accounts for a major part of construction costs. We carry out investigations to develop the new ship design system to support the decision-making of designers, to enhance the reliability of structural strength, and to incorporate knowledge of construction and design.

  • Strength of Materials Fracture Mechanics Structural Analysis
  • Research
  • The effects of several parameters related to fatigue strength, i.e. material, mechanical, shape and environmental factors, must be understood quantitatively in order to estimate the fatigue strength of welded structures accurately and to develop new materials or components with excellent resistance to fatigue failure. To accomplish this, we carry out investigations to establish a method to evaluate fatigue strength experimentally and theoretically.
