The large 3D vibration table has been featured in the newspaper.

The largest large-scale shaking table in the country can reproduce seismic motions such as those from the Great East Japan Earthquake, which are difficult for other companies to replicate, with 100% accuracy! In addition to seismic resistance testing, transportation tests can also be conducted.

The Japan Oceanographic Science YOKOHAMA LAB (Isogo Ward, Yokohama City, Kanagawa Prefecture) conducts commissioned vibration tests, including the reproduction of various seismic waveforms such as those from the Great East Japan Earthquake. It provides data necessary for strength calculation verification of products requiring seismic performance, including acceleration response spectra, acceleration time histories, displacements, and resonance points, enabling advanced evaluation tests. *Due to a company split, the vibration table business of MTI Co., Ltd. was transferred to Japan Oceanographic Science Co., Ltd. in April 2022. The shaking table is large, measuring 2.6×6.2m, and can perform 2-hour vibrations with minimal waiting time for multiple vibrations (with a maximum of 123 vibrations per day in the past). It also accommodates actual transport vibrations from trailers, railways, and ships, as well as transportation vibration tests according to JIS and ASTM standards. The photo shows a test using approximately 8 tons of water (published with permission from Ace Water Co., Ltd.). 【Actual Earthquake Waveforms】 Great East Japan Earthquake / Niigata Chuetsu Earthquake / Hanshin Earthquake / Noto Peninsula Earthquake, etc. 【Artificial Earthquake Waves Held】 ○ NTT Docomo artificial earthquake waves, NTT ○ NEBS (GR-63-CORE zone4) 【Transportation Standard Tests】 ○ JIS Z 0200/0232, ASTM D4169, etc. ● For more details, please contact us.

Faithfully reproduce the vibrations of cargo during transportation!

At the Yokohama Lab of Japan Marine Science (located in Isogo Ward, Yokohama City, Kanagawa Prefecture), we contribute to the examination of optimal loading methods for transported cargo and the investigation of damage causes by reproducing the vibrations and motions that cargo encounters during transport for testing. *Due to a company split, the demonstration testing business utilizing the vibration table of MTI Co., Ltd. was succeeded by Japan Marine Science Co., Ltd. as of April 1, 2022. We have established a system to conduct vibration tests that meet the newly added standards applicable to IBC containers for storing liquid hazardous materials manufactured, repaired, or modified after January 1, 2011. (This vibration test has also been confirmed by the Japan Ship Equipment Inspection Association as of the end of August 2010.) 【Actual transport vibration waves held (for cargo vibration reproduction testing)】 Rail transport vibration wave: Vibration of double-stack trains on North American inland cross-continental railroads Trailer transport vibration wave: Vibration of trailers traveling on metropolitan expressways 【Standard vibration waves held】 JIS Z 0232 ● For more details, please download the catalog or contact us.
