A Study on Forced Vibration of Double Bottom Structure due to Whipping on an Ultra Large Container Ship
Autor: Yohei Kawasaki, Ichiro Amaya, Tetsuji Miyashita, Tomoki Nagashima, Tetsuo Okada, Hiroaki Kobayakawa, Isao Neki
Publikováno v: Volume 3A: Structures, Safety and Reliability.
Worldwide expansion of economy has brought about prominent and rapid enlargement of container ships. Their greater beam has caused more flexible double bottom structure, giving rise to concerns about its adverse effect to the ultimate strength of hul

Identification Method of Damping for Ship Structural Vibration (2nd Report)
Autor: Hiroki Kusumoto, Yu Takeda, Isao Neki
Publikováno v: Journal of the Society of Naval Architects of Japan. 2002:283-290
In order to prevent harmful vibration in ships at the early stage of design, anti-vibration design is required on the basis of accurate estimation methods. To investigate vibration response of superstructure, very large scale of 3-dimensional finite

Optimum Structural Design Using Genetic Algorithm and Finite Element Method
Autor: Isao Neki, Tetsuo Okada
Publikováno v: Journal of the Society of Naval Architects of Japan. 1995:327-338
Finite element method has become a popular practical tool of the assessment of hull strength for structural designers. However, structural optimization using finite element analysis is not yet a usual practice in actual hull design. The obstacles to

Development of New Finite Element by Source Method
Autor: Isao Neki, Tsuyoshi Tada
Publikováno v: Journal of the Society of Naval Architects of Japan. 1995:357-362
A new Finite Element by Source method (FES) is developed by the authors. FES which has flexible geometrical shape is composed by nodes distributed on the element boundary and sources distributed out of the element boundary. The relation between the d

Development of Computer-Aided Process Planning System for Plate Bending by Line Heating (Report 3)—Relation Between Heating Condition and Deformation
Autor: Yukio Ueda, Hidekazu Murakawa, Ahmed Mohamed Rashwan, Isao Neki, Ryoichi Kamichika, Morinobu Ishiyama, Jun-ichiro Ogawa
Publikováno v: Journal of Ship Production. 10:248-257
An effective plate bending process by line heating can be achieved when the heating conditions are properly selected to produce desirable bending or inplane deformations. To make such decisions on he heating condition, the relation between heating co

A Simulation Analysis on the Thermal Elasto-Plastic Deformation of Steel Plate by High Frequency Induction Heating
Autor: Jun-ichiro Ogawa, Isao Neki, Ryoichi Kamichika
Publikováno v: Journal of the Society of Naval Architects of Japan. 1993:535-542
In order to estimate temperature history in steel plate induced by high frequency induction heating, eddy current analysis and transient heat conduction analysis are combined. Also, thermal elasto-plastic FEM analysis is conducted using multi-layered

Optimization of Ship Structural Design by Genetic Algorithm
Autor: Tetsuo Okada, Isao Neki
Publikováno v: Journal of the Society of Naval Architects of Japan. 1992:259-266
In general, ship basic design is based on design-spiral approach where variable design parameters are defined through repetition of trial and error. This kind of approach is a process of satisfying a lot of complicated design criteria empirically, ra
