铁道混凝土枕轨下用50-10-9型橡胶垫板静刚度的初步探讨

研究了橡胶垫板静刚度的影响因素,做了不同配方的橡胶垫板的静刚度试验,研究结果表明:模具沟槽结构的不一致性是垫板静刚度不完全一致的原因之一;微晶蜡与si-1对橡胶垫板静刚度的影响不同,微晶蜡在一定程度上降低垫板的静刚度,而Si-1偶联剂对垫板的静刚度有利。

The influencing factors of the static stiffness of the rubber plate were studied. Different formulations of the rubber plate for static stiffness were carried out. The results show that： Inconsistency in mould groove structure is one of the reason of not completely consistent on the static stiffness of the plate; the static stiffness of the rubber plate were affected differently by microcrystalline wax and Si-1. The static stiffnes of plate can be reduced by microcrystalline wax,howerer, Si-1 coupling agent is beneficial to the static stiffness of the rubber plate.
