Seismic testing, vibration testing (large-scale three-dimensional vibration testing)

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.

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 two 20ft containers. - The horizontal stroke is ±200mm, the vertical stroke is ±250mm, and the maximum tilt angle is 20 degrees, allowing for dynamic movement. - The maximum load capacity is 20 tons, and even at a 5-ton load, the maximum acceleration is 3G vertically and 2G horizontally. Due to these characteristics, it is capable of: - Reproducing transportation vibrations from ships, trains, and trailers, - As well as fully replicating seismic motions from events such as the Great East Japan Earthquake and the Hanshin-Awaji Earthquake.
