对动态力学性能和静态力学性能的关系进行了理论分析,认为二者之间存在对应关系。通过对采用动态力学分析(DMA)法得到的动态储能模量主曲线和材料试验机得到的静态松弛主曲线进行对比,验证了这种关系。提出了根据动态和静态力学性能关系,利用动态储能模量主曲线得到静态松弛模量和静态强度,以评估推进剂老化状态的非破坏性方法。预测值和实测值的比较结果显示,该方法能够较好地评估推进剂的寿命状态。 The relationship between dynamic mechanical properties and static mechanical properties is analyzed theoretically, and there is a corresponding relationship between the two. This relationship is verified by comparing the dynamic relaxation modal master curve obtained by dynamic mechanical analysis (DMA) with the static relaxation master curve obtained by the material testing machine. Based on the relationship between dynamic and static mechanical properties, a static non-destructive method to evaluate the aging state of propellants by using the main curve of dynamic storage modulus was proposed. The comparison between the predicted value and the measured value shows that this method can well evaluate the life status of the propellant.
