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.
