In this study, we evaluated the compressive properties of soft rubber using the modified split Hopkinson pressure bar method. The soft rubber is used to cover the ink roll surface of a press, and is subjected to impulsive loading each time the roll rotates and contacts another roll. In carrying out the experiment, first, strain waves in pressure bars made of PMMA were investigated and actual strain applied to a specimen was estimated using the transfer function which calculated the dispersion characteristics of strain waves in the pressure bars. Second, the soft rubber was tested using PMMA pressure bars, the obtained strain was processed by the transfer function, the dynamic stress-strain curves of the soft rubber were obtained, and strain rate dependency on the stress-strain curves was investigated. Third, the determination of the constitutive equation of the soft rubber using the Voigt model was carried out, and stiffness and damping parameters were identified.
