| 中文摘要: |
| 利用硫化橡胶拉伸试验数据和EXCEL软件，采用梯形网格法和曲线拟合法两种方法计算硫化橡胶应变能（硫化橡胶在拉伸或压缩过程中功转化成的内能）。两种方法所得结果均准确、可靠。原始数据采集密度越大，硫化橡胶应变能计算结果越准确。 |
| 英文摘要: |
| The strain energy of vulcanized rubber（stored internal energy converted from the stretching or
compression of vulcanized rubber） was calculated by trapezoid grid method and curve fitting method using
tensile test data and EXCEL software. The results of the two methods were accurate and reliable. The higher
the collected raw data density was，the more accurate the calculation results of the strain energy would be. |
