National Treasure Bronze Amida Buddha Sitting Statue Preservation and Repair Vibration Characteristics Investigation Continuous Micro-Movement Survey

We were able to obtain valuable data that is highly accurate and reliable!

We would like to introduce the "Vibration Characteristics Survey for the National Treasure Bronze Amida Nyorai Sitting Statue." We conducted continuous micro-vibration measurements of the statue and assisted the Tokyo National Research Institute for Cultural Properties in their investigation. This time, we aimed to understand the natural period and vibration characteristics of the statue, which is equipped with a sliding seismic isolation device made of stainless steel, and we conducted this survey simultaneously. 【Survey Overview】 - Continuous micro-vibration measurements were conducted using a highly sensitive servo-type velocimeter (Tokyo Sokushin), measuring 24 components simultaneously at 8 locations with 3 components each. - We analyzed these velocity waveforms (transfer functions and Fourier spectra) to grasp the natural frequencies and dynamic characteristics. - By using 24 highly sensitive servo-type velocimeters (Tokyo Sokushin) for simultaneous measurements, we were able to obtain highly accurate and reliable valuable data. *For more details, please download the PDF or feel free to contact us.
