The model of rate-dependent mechanical behavior for the damping rubber material is proposed based on Petiteau’s time convolution integral model in terms of the K-BKZ model and Xiang’s constitutive model to characterize the hyperelastic response under various deformation states. Furthermore, the specimen of PVMQ with different Phenyl contents were prepared, and the mechanical behaviors of the samples were tested at various strain rates. Within a small stretch ratio, the materials are mainly characterized by elastic or hyperelastic behaviors rather than viscous behavior. When the material’s stretch beyond the elastic section, the viscous behavior gradually manifests itself and the materials are showing sensitivity to strain rates. With the increase of phenyl content in the materials, the influence of strain rate will be weakened. The model can characterize the mechanical behaviour of the damping materials accurately under various strain rates. In addition, this viscoelastic model could be used to predict the mechanical response of Phenyl silicone rubber in the dynamic mechanical environments.
