Evaluation of the rebound and vibration absorption properties of rubber materials

Introduction of examples of "temperature dispersion measurement" and "frequency dispersion measurement - master curve."

We would like to introduce a case where the rebound and vibration absorption properties of rubber materials were evaluated using dynamic mechanical analysis (DMA). In the "Comparison of Vibration Absorption of Rubber (Temperature Dispersion Measurement)," dynamic mechanical analysis was conducted using two types of rubber materials. Rubber A is considered to have superior vibration absorption properties (lower rebound) than Rubber B, with larger E" and tanδ in temperature ranges above -10°C. In the "Comparison of Vibration Absorption of Rubber (Frequency Dispersion Measurement - Master Curve)," the dynamic mechanical properties of Rubber A and B were compared across frequencies. By creating a master curve, it is also possible to predict the viscoelastic behavior in frequency ranges that cannot be directly measured. 【Measurement Details】 ■ Comparison of Vibration Absorption of Rubber (Temperature Dispersion Measurement) - Rubber A is considered to have superior vibration absorption properties (lower rebound) than Rubber B, with larger E" and tanδ in temperature ranges above -10°C. ■ Comparison of Vibration Absorption of Rubber (Frequency Dispersion Measurement - Master Curve) - Rubber A is considered to have superior vibration absorption properties than Rubber B, with larger tanδ across a wider frequency range. *For more details, please download the PDF or feel free to contact us.
