Simulation on Vibration Isolation System for Vibratory-Drum Test Stand

the reliability and vibration performance test of vibratory rollers have been done in the test field to ensure that the vibratory roller meet the quality requirement. At present, the indoor test stand for vibratory roller has not yet been studied at home and abroad. This paper designs the indoor test stand for vibratory roller and makes simulation analysis by the numerical model of vibration-drum and test stand. The vibration isolation system of test stand is determined as a function of the test stand mass (m2), the stiffness of rubber tire (k1) and the stiffness of the vibration isolation block (k2). The test results showed that the vibration drum-test stand model can account for the vibration isolation system.
