%X 通过动态加载应变试验，分析了钢丝绳芯橡胶输送带在0，10，20，30和40℃温度下的应力响应。以输送带的标准固体本构模型为基础，通过黏弹性材料的傅里叶级数拟合，推导了输送带标准固体模型中3个参数的识别公式，建立了3个参数随温度变化的拟合公式，并分析了其随温度的变化特性。结果表明：温度对黏度系数η1和弹性模量E1影响较大，呈非线性变化趋势；对弹性模量E2影响相对较小，可以近似为线性变化。最后，通过试验对建立的拟合公式误差进行了分析，最大误差约为3%，试验结果也证明了辨识公式的准确性。<br>The stress responses of the rubber belt with steel rope core under 0℃, 10℃, 20℃, 30℃ and 40℃ are analyzed by employing the dynamic loading stress experiment. Based on the constitutive model of the belt standard solid, the identification equations of the 3 parameters for the belt standard solid are derived by the Fourier series fitting method for the viscoelastic material, and the fitting equations with the temperature variation for the 3 parameters are established. The variation performance with temperature for the 3 parameters are analyzed, the results show that the temperature obviously influences the viscosity coefficient η1 and the elastic modulus E1, and the trends are nonlinear, but the influence from the temperature to the elastic modulus E2 is small and the trend is linear. Finally, the error analysis of the fitting equations is performed by the experiment, and the maximum error is about 3%. The experiment results prove the accuracy of the identification equations.
