摘　　要：以APU隔振器为研究对象,提出采用五参数分数导数建立橡胶隔振器本构模型。推导了含橡胶隔振器振动系统的非线性动力学有限元方程式。分析了隔振器结构参数变化对传递率特性的影响。研究结果表明:文中的数值计算方法能更好地预测含橡胶隔振器振动系统的动态特性。A nonlinear dynamics constitutive model of rubber isolator is established by making use of five-parameter fractional derivative. The finite element formulation of vibration system with rubber iso- lator is derived. The transmissibility characteristics are study by changing the structure parameters of isolator. Results show that the dynamic properties of vibration system with rubber isolator can be predic- ted by the numerical calculation methods.
