摘　　要：基于有限元方法模拟研究硅橡胶泡沫材料与刚性接触面在准静态摩擦接触过程中的力学性能。基于多尺度方法建立与实际泡孔结构相符的细观模型-单胞泡孔模型。考虑泡孔壁之间摩擦因素,计算获得细观模型的力学性能。将细观模型性能通过数据传递机制植入宏观模型,据此模拟研究硅橡胶泡沫材料与刚性加载面相互作用时的压缩载荷和结构变形情况,并讨论界面摩擦因数对该材料力学性能的影响。模拟结果表明,摩擦因数对硅橡胶泡沫材料的准静态单轴压缩力学性能影响较小,且所得模拟结果与实验结果吻合良好。Utilizing the finite element method,the mechanical behaviors of the silicon rubber foam frictional contact with the rigid surfaces under the quasi-static condition was studied in the present work.Based on the muhi-seale method,the microscale model-the unit cell model was set up and its stress response was investigated,considering the friction between the cell walls.The obtained results in the micro-scale model were implanted into the macro-scale model by the data transferring mechanism.The quasi-static contact of the silicon rubber foam with the rigid surfaces was simulated to analyze the load and structure deformation,considering the friction between the specimen and the rigid surfaces.The simulation data reveal that the friction affects the results quit limited both in the micro-and macro-scale models,and the present results agree with test data well.
