Experimental Investigation on Vibration Performance of Polyurethane Foam Plastic

  • Publish Date: 25 Aug 2003
  • An experimental device of the vibration performance of foam plastic was set up. The vibration test of a reinforced plastic material was carried out. Experimental results show that the vibration performance of this foam plastic material has relation not only to vibration amplitude but to exciting frequency. The restoring force of the foam plastic material is influenced by exciting frequency, vibration amplitude and deformation history. The foam plastic material has a nonlinear hysteretic characteristic. In vibration conditions, stiffness and damping characteristics of the foam plastic material are nonlinear. The research lays a foundation for modeling and parameters identification, dynamic design and dynamic optimization of the vibration-isolation material.
