TEST APPARATUS FOR MEASURING VIBRATION-DAMPING PROPERTIES OF MATERIALS USING ACOUSTIC VIBRATION

摘要

An apparatus for measuring vibration property by using acoustic vibration is provided to easily vibrate any material and improve accuracy in the measurement result by not using an auxiliary sample. An apparatus for measuring vibration property of a material by using acoustic vibration includes a material sample fixing apparatus unit, a vibration sensor, and a sound wave generating unit(20). The material sample fixing apparatus unit fixes one side part of a material sample, and the vibration sensor is placed adjacently to one side part of the material sample, and the sound wave output end of the sound wave generating unit is placed adjacently to the other side part of the material sample. The vibration property of the material sample is measured by measuring the response signal as to the vibration by the sound wave generating unit with the vibration sensor.
