Development of Automated Test Equipment to Improve the Measurement Uncertainty of Seismic Acceleration Sensors: Focusing on Tilting-Type Equipment

Development of Automated Test Equipment to Improve the Measurement Uncertainty of Seismic Acceleration Sensors: Focusing on Tilting-Type Equipment

This study developed an automated seismic acceleration sensor test equipment to improve the high measurement uncertainty of existing test equipment with the tilting method. The equipment was developed by setting the legal standards for seismic acceleration sensor test equipment and the problems of existing test equipment as performance indicators. The problems with the existing test equipment, which was manually operated, included measurement error owing to handling vibration, occurrence of angle error according to the observation field, and measurement method without considering hysteresis. The developed equipment satisfied the legal standards, and the problem of measurement error owing to handling vibration and angle error according to the observation field of view was improved by attaching a servo motor and precision level to the measurement equipment. Hysteresis control has been improved by adding the delay time control function of dedicated software (S/W). The developed automated seismic acceleration sensor test equipment can be used for the testing of seismic acceleration sensors, and the operating software reduced measurement uncertainty in the testing of seismic acceleration sensors.
