【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 .更多还原

【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.更多还原
