Abstract:
The four-pole parameter model of the isolation system was established to study the effect of the main parameters, such as middle mass and stiffness of the isolator, on the vibration isolation of the system by using the four-pole parameter method, and the principle which could be referenced in the design work was presented. The research shows that the middle mass should be chosen within a proper range based on the vibration isolation index requirement, and the isolators could be the same under the premise that the middle mass is lesser.
