Lab of Vibration and Gravity is responsible for research, establishment and maintenance of national measurement standard measuring devices in the field of Vibration & Shock,Gravity, traffic speed, wind speed and rotational speed. The laboratory consists of three working groups: Vibration & Shock group, Speed measurement group and Gravity group.

  • New Generation of Vibration National Standards

    The new generation of vibration national standards is accordance with ISO 16063-1, We realized the units of acceleration in the frequency range from 0.1 Hz to 50 kHz using standard measuring devices (national standards) which generate and measure...

International Cooperation

  • NIM is an official member of Consultative Committee for Acoustics, Ultrasound and Vibration (CCAUV), CIPM and also a member of Working Group for Key Comparisons (CCAUV-KCWG) and Working Group on Strategic Planning (CCAUV-SPWG).

  • NIM was the participant of CCAUV Key Comparison: CCAUV.V-K1.1 and CCAUV.V-K2, and the pilot lab of APMP TCAUV Key Comparison APMP.AUV.V-K1.2 and Supplementary Comparison APMP.AUV.V-S1.

  • NIM was responsible, together with CMS, Taiwan, for APMP TC Initiative Project ‘Joint Research Project on Primary Shock Acceleration Comparison with Laser Interferometry’ from 2010 to 2011. The fruitful research outputs and successful cooperation...

  • Would-be Host and Pilot Global International Key Comparison of Absolute Gravimeters in 2017 nominated by CIPM.
