  • The dynamic model of nonlinear fractional derivatives was established for the research of an auxiliary power unit(APU) rubber isolator.The parallel model of five-parameter fractional derivative was presented,which concerned frequency and amplitude dependencies.The model can simulate viscoelastic properties in a wide range with few parameters.At the same time,the influence of every parameter on dynamic modulus and loss modulus as well as the methods of numerical solution were studied.The result shows that the model can be used to predict the dynamic properties in a wide range.It provided basis for design and application of rubber isolator.
