摘要：
Following the finite element analysis and the experimental verification, the vertical stiffness of thrust rod for heavy-duty vehicles is analyzed, the influence of rubber compressibility on the simulation result is taken into consideration, and the structure of the thrust rod is optimized. Uniaxial tension test for rubber specimens is conducted to obtain the strain-stress data, by which the parameters of the deviatoric term are fitted. The parameters of the volumetric term are described by Poisson's ratio. And the compressibility can be adjusted by changing the value of Poisson's ratio. It shows that the compressibility exerts an important effect on the finite element simulation result, and the stiffness of the thrust rod increases with Poisson's ratio increasing. The stiffness of the thrust rod increases linearly when Poisson's ratio is less than 0.495, and it increases rapidly as Poisson's ratio is larger than 0.495. When Poisson's ratio is 0.492, the results of simulation and experiment coincide well. It indicates that modification of rubber compressibility by adjusting Poisson's ratio is reasonable. © 2017, Editorial Office of Journal of Xi'an Jiaotong University. All right reserved.
