摘    要:对两种硅橡胶材料O形圈的载荷衰减规律进行了试验研究,结果发现,O形圈的载荷衰减规律与O形圈材料的性能有关;温度对O形圈的衰减规律也有很大影响,温度越高,O形圈的载荷衰减速度越快.在试验的基础上对O形圈载荷衰减的理论模型进行了研究,采用无穷多个Maxwell模型并联的方式,找到了一个能较好地表示O形圈载荷衰减规律的模型. 

关 键 词:硅橡胶   载荷分析   麦克斯韦尔体   O形圈

Abstract:Experimental research on load decay of two kinds of O ring made of different silicone rubber under different temperature has been conducted. The results show that the load decay characteristic of the O ring is related to the material of the O ring, and temperature can change load decay characteristic, the speed of load decay increases with the rise of O ring temperature. By the study to the theory of load decay and analysis to the results of experiments, a theoretical model has been conducted to describe the load decay characteristic of the O ring,it matches the results of the experiments very well.
Keywords:silicone rubber  loading analysis  Maxwell model  O ring
