丁基橡胶阻尼材料相容性的DSC与DMA研究

The compatibility of the IIR damping material was studied by use of DSC and DMA methods.The results is that the compatibility is very good between IIR and the resin vulcanizing reagent and there is only one mount in the charts of DSC or DMA.The studies of the results is very significant for the study on the damping characteristic of the damping materials.At the same time,we also discussed the reason through analysing the two molecular structures.

环状丁基橡胶结构件压缩特性

橡胶件在工程上有着广泛的应用，例如机床车辆、船舶、汽车、飞机、桥梁及仪表等。由于橡胶件良好的减振作用，近年来也尝试应用于工程结构设计中。本例即为采用橡胶材料的压缩环作为工程支承结构件，其作用原理为(见图1)：利用橡胶的“不可压缩性”(承载变形时仅仅是形状的改变，而体积几乎保持不变)，将压缩环置于规定形状空间内，对压缩环施加轴向载荷，使其产生径向扩张，从而对被支承件产生径向支承作用，同时还可起减振作用。
