日本海洋科学 Company Profile

During this tour, we will introduce the following equipment owned by our company: - Motion capture (displacement detection using special camera images) - Laser displacement meter - Seismometer - 20ft container for transportation vibration testing - Testing video recording system In addition, we plan to showcase various demonstration vibrations as described below. 【Demonstration Vibration Content (Proposal)】 - Demo Vibration 1: Resonance Point Exploration Sine wave sweep, random vibration - Demo Vibration 2: Actual Earthquake Waves Hanshin-Awaji Earthquake, Niigata Chuetsu Earthquake, Great East Japan Earthquake - Demo Vibration 3: Artificial Earthquake Waves NEBS Zone 4, NTT Docomo R12 - Demo Vibration 4: Transportation Vibration Standards JIS Z 0232 Z direction - Demo Vibration 5: Transportation Vibration Reproduction Metropolitan Expressway trailer, North American double-stack train, automobile transport ship rolling - Demo Vibration 6: Others Shock wave horizontal 2G, vertical 3G Sine wave vibration in inclined state (inclination angle 12 degrees) Rolling test (maximum inclination ±18 degrees) Additionally, we can provide vibration testing of test specimens using demonstration vibrations for one company on a first-come, first-served basis, and we also welcome other companies in the same industry under the condition of mutual visits. Limited to the first 50 participants. We encourage everyone to participate. *Photography and video recording will also be allowed inside the testing facility on the day of the event.

The first demonstration vibration observation event was held on June 29, 2023, with a total of 53 participants, including 46 general participants and 7 media representatives, and it was a great success. However, for this first observation event, we had to close applications, and in addition, according to the survey from the first observation event, the demonstration vibration observation event was very well received, so we will be holding a second demonstration vibration observation event. In this observation event, we will introduce the following equipment owned by our company: - Motion capture (displacement detection using special camera images) - Laser displacement meter - Seismometer - 20ft container for transportation vibration testing - Test video recording system We also plan to show various demonstration vibrations (Note: For safety reasons, participants will not be able to experience earthquakes by standing on the vibration table). For details on the demonstration vibration content and to apply, please refer to the "Details/Application" section below. Everyone, we look forward to your enthusiastic participation.

Our large three-dimensional shaking table, owned by our company and located in Yokohama, was featured in the "Nihon Kaiji Shimbun" for two consecutive days. This equipment has the following features: - It has a fixed platform measuring 2.6m x 6.2m and is tall enough to stack 20ft containers in two layers. - The horizontal stroke is ±200mm, the vertical stroke is ±250mm, and the maximum tilt angle is 20 degrees, allowing for dynamic movements. - The maximum load capacity is 20 tons, and even at a 5-ton load, the maximum acceleration is 3G in the vertical direction and 2G in the horizontal direction. Because of these features, it can not only reproduce transportation vibrations from ships, railways, and trailers but also fully replicate seismic motions from events such as the Great East Japan Earthquake and the Hanshin-Awaji Earthquake.
