| Abstract: |
| Numerical analyses are made in this paper to simulate viscoelastic responses of multi-body systems under external loads by using the method developed by the authors. Through comparative computations, the effects of viscous damping on the deformation and movement behavior as well as interaction behavior of the multiple-bodies systems are examined. Verification of the method is made by a comparative study on a given example with the general FEM software ABAQUS. From the comparison, it is found that these two methods can obtain the almost same deformations and movements, however contact stresses got by the proposed method are more reasonable because that section by section of uniform distribution of contact stresses in ABAQUS can be overcome. |
