日本海洋科学 Company Profile

In this tour, we will introduce the following equipment owned by our company: - Motion capture (displacement detection using special camera images) - Laser displacement gauge - Seismometer - 20ft container for transport vibration testing - Test video recording system In addition, we plan to showcase various demonstration vibrations as described below. 【Demonstration Vibration Content (Draft)】 - 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: Transport Vibration Standards JIS Z 0232 Z direction - Demo Vibration 5: Reproduction of Transport Vibration Metropolitan Expressway trailer, North American double-stack train, automobile transport ship rolling - Demo Vibration 6: Others Shock waves: horizontal 2G, vertical 3G Sine wave vibration in inclined state (inclination angle 12 degrees) Rolling test (maximum inclination ±18 degrees) Furthermore, we can also provide vibration testing of test specimens using demonstration vibrations for one company on a first-come, first-served basis, and we 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 within the testing facility will also be permitted on the day of the event.

The first demonstration vibration observation event was held on June 29, 2023, with 46 general participants and 7 media representatives, totaling 53 attendees, 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 was very well received, so we will hold the 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 transport vibration testing - Test video recording system We also plan to showcase 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 encourage you to participate actively.

Japan Agency for Marine-Earth Science and Technology will hold its first free public tour featuring a large vibration table. 【Features of the testing facility】 - Large size with a base plate of 6.2×2.6m and capable of accommodating a 20ft container - Large stroke of ±250mm vertically and ±200mm horizontally → This allows for the reproduction of significant real earthquakes (e.g., the Hanshin-Awaji earthquake), making it incredibly impressive!! - Large excitation forces of 1200kN vertically and 464kN horizontally - Capable of testing liquid-filled cargo and long-duration continuous excitation → As it is a hydraulic testing machine, it can accommodate a wide range of requests!!
