Aiming at the problem of high vibration and noise of rubber roller hulling, the vibration isolation technology of rubber roller hulling impact isolation system was studied. Firstly, the mechanical impact excitation generated during the operation of the hulling device is determined as the main excitation source of hulling operation, and then the force amplitude of the excitation force is calculated through theoretical solution. Then, according to the working characteristics of rubber roller hulling and the requirements of reducing vibration transmission, an impact isolation system composed of impact isolators in parallel is proposed. Finally, the static compression characteristics and torsional characteristics of the impact isolation system are simulated and analyzed in ADAMS to verify the stability of the impact isolation system. The dynamic simulation analysis of the impact isolation system under pulse impact is carried out, and the displacement curve of the cot under pulse impact and the stress curve of the cot installation shaft disc are obtained. Comparing the maximum stress of cot installation shaft disc with the theoretically calculated excitation force amplitude, it is obtained that the transmission rate of the excitation force after installing the impact isolation system is 49.5%, It is verified that installing the impact isolation system composed of impact isolators in parallel in the cot has a beneficial effect on reducing the transmission of vibration.
