从材料特性、力学行为特征、本构模型和实验手段四个方面详细论述了浇注高聚物粘结炸药（PBX）力学性能的研究进展，指出动态力学测试及材料本构是目前研究浇注PBX的热点和难点。认为可以通过借鉴粘弹性模型、橡胶超弹性模型及推进剂模型建立浇注PBX的本构模型，并指出需要结合浇注PBX含能敏感、软材料和大变形特性来选择和改进现有的测试技术。对力学性能预测、动态实验技术及数值模拟等方面需要开展的工作提出了一些看法。

Properties of cast PBXs are reviewed including mechanical behaviors, material characteristics, experimental techniques and constitutive models.Some hot-spots and difficulties such as dynamical mechanical properties analysis and constitutive models are summerized.The enablishment of the models of cast PBXs may refer to Visco-elastic models, hyper-elastic models and the constitutive model of solid properlants.Characteristics of energetic sensitivity, soft material and large deformation are suggested to improve the experimental methods.The directions for future research are also forecasted, such as estimation of mechanical proper-ties, dynamic testing methods and numerical simulation.
