硫化橡胶应变能的计算方法

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。;The vulcanized rubber strain energy（internal energy from the vulcanized rubber work conversion during stretching or compressing）was calculated by trapezoid grid method and curve fitting method using vulcanized rubber tensile test datas and EXCEL software.The results of the two methods were accurate and reliable.The higher the raw data collection density was，the more accurate the calculation results of vulcanized rubber strain energy would be
