O形橡胶密封圈室温拉伸试验装置及测试方法的研究

Research on Room Temperature Tensile Test Device and Test Method for Rubber O-Ring

针对完整O形橡胶密封圈室温拉伸试验,开发了新型试验装置及试样拉断伸长率的测试方法。试验结果表明,新型试验装置结构简单、操作方便、测试精度高、测量稳定,可满足完整O形橡胶密封圈室温拉伸试验中拉断伸长率测试的要求。

A new test device and a test method for the tensile test of rubber O-rings at room temperature were developed,and the elongation at break of the samples could be accurately measured.The test results showed that the new test device had the advantages of simple structure,convenient operation,high test accuracy and stable measurement,which could meet the requirements of measuring the elongation at break of the complete rubber O-ring in room temperature tensile test.
