Static stiffness as one of key parameter to evaluate the bearing capacity of rubber absorber, is the principal evaluating index while design and produce. In order to analyze the whole static stiffness of rubber absorber, firstly, static stiffness model was calculated based on the stiffness theory of rubber. Then, software of finite element analysis of Abaqus is used to calculate the static stiffness model. The calculate results shows that the difference between theoretical calculation res-ult and finite analysis result is not great, which indicate that the static stiffness model is reasonable. Finally, constraint condi-tion under cabin environment is established, compact design of rubber absorber which based on the static stiffness model and constraint condition has been finished.%静刚度作为评价橡胶减振器整体性能的主要参数,是减振器产品设计的关键指标之一.本文通过理论推导建立橡胶减振器静刚度计算模型,使用Abaqus有限元仿真软件对静刚度模型计算结果进行验证,证明了刚度计算理论的正确性.接着以静刚度模型为设计基础,建立舱室环境下橡胶减振器的约束条件,实现了在额定静刚度和限位器高度下橡胶减振器的结构尺寸设计.
