Evaluation of the rebound and vibration absorption properties of rubber materials.
アイテス
To prevent shock and vibration, low-rebound and vibration-absorbing materials are used in various situations. The indicator of these properties is viscoelasticity. This document presents examples of evaluating the rebound and vibration absorption properties of rubber materials through dynamic mechanical analysis (DMA). From the dynamic viscoelasticity concerning temperature, it is possible to predict the vibration absorption and rebound properties of materials in their usage environment. From the dynamic viscoelasticity concerning frequency, it can be utilized to predict damping performance against seismic motion, braking performance of tires, and in the low-frequency range, it can be used to predict long-term deformation behavior such as creep.
