Study on Fatigue Reliability and Inspection of Ship Structures Based on Enquete Information
Autor: Katsuo Ohtaka, Yukio Fujimoto, Eiji Shintaku, Sung Chan Kim
Publikováno v: Journal of the Society of Naval Architects of Japan. 1996:601-609
Fatigue reliability analysis under repeated inspections is carried out for the six structural members of bulk carrier. Crack initiation and propagation properties of the members, probability of crack detection by the visual inspection, target failure

Prediction and Prevention of Vibration of Stiffened Plates (1st Report)
Autor: Yukitaka Yasuzawa, Hiroshi Nishino, Katsuo Ohtaka
Publikováno v: Journal of the Society of Naval Architects of Japan. 1992:447-463
Vibration of unidirectionally stiffened plate is investigated by means of the calculation based on finite element method and developed by the authors. In order to examine the relative stiffness of stiffeners to that of panels between stifferers, the

A Study of Wave-Induced Vibrations (1st report)
Autor: Katsuo Ohtaka, Masao Ushijima, Koji Kagawa
Publikováno v: Journal of the Society of Naval Architects of Japan. 1975:246-253
Wave-induced vibrations (springing) have been studied both theoretically and experimentally. The model experiments have been carried out using a tanker model of 7 meter length. Higher harmonic excitation in regular waves (which means the exciting for

Study on Vibratory Response of Deck in Superstructure
Autor: Katsuo Ohtaka, Kazunobu Fujita, Masao Miyoshi, Tsuyoshi Kabata, Koji Kagawa
Publikováno v: Journal of the Society of Naval Architects of Japan. 1986:433-442
In general the design of deck panels is performed to be tuned of the lowest natural frequency of panels over frequencies in exciting forces. Recent passenger ships or some types of research ships with wide area for more accomodations, however, result

Vibration of Container Ship
Autor: Kenji Miyamoto, Koji Kagawa, Kazuo Umezaki, Katsuo Ohtaka
Publikováno v: Journal of the Society of Naval Architects of Japan. 1969:187-207
The vibration of a container ship has been studied with a chief attention to the horizontal and the torsional vibrations. Some checks on the problems of structural behaviour and of the added virtual mass of water have been made. Centre of virtual mas

Measurements of the Propeller-Induced Vibratory Forces on a Destroyer
Autor: Katsuo Ohtaka, Kaname Taniguchi
Publikováno v: Journal of Zosen Kiokai. 1963:138-147
Measurements of the propeller-induced oscillating pressures induced on the hull surface were made on a destroyer in her sea trial and the results were compared with those of the model tests previously made by one of the authors. Both results agreed w

A Study of Horizontal and Torsional Vibration of Ships (1st Report)
Autor: Masao Ushijima, Katsuo Ohtaka, Toyoji Kumai
Publikováno v: Journal of Zosen Kiokai. 1967:183-197
The numerical solution techique was applied to the equations of the coupled torsion-horizontal vibration of a beam, and the computing program by means of a digital computer was made.Using the above-mentioned program, preliminary calculations were mad
