摘　　要：以不同粒径的炭黑、白炭黑、陶土及碳酸钙为填料加到乙丙橡胶中制备轨道减振橡胶垫板,研究了不同填料及粒径对垫板动静刚度比的影响。结果表明,使用炭黑时动静刚度比随粒径增大而减小,使用白炭黑时动静刚度比随粒径增大而增大,而使用陶土和碳酸钙时动静刚度比随粒径变化无规律且变化较小。同时,使用补强型填料炭黑和白炭黑时,垫板动静刚度比比使用填充型填料时的动静刚度比较高。A track vibration damping rubber pad was prepared by adding carbon black,white carbon black,clay,and calcium carbonate with different particle sizes as fillers to ethylene propylene rubber.The influence of different fillers and particle sizes on the dynamic and static stiffness ratio of the pad was studied.The results showed that the dynamic to static stiffness ratio decreased with increasing particle size when using carbon black,increased with increasing particle size when using white carbon black,and varied irregularly and minimally with increasing particle size when using clay and calcium carbonate.Meanwhile,when using reinforcing fillers such as carbon black and white carbon black,the dynamic and static stiffness of the pad is higher than when using filling fillers.
