摘　　要：采用Material Studio分子模拟分析软件,对两种粘弹性阻尼材料A和B静压力条件下的自由体积参数进行预测。预测结果显示,两种材料均随着静压力的提升出现自由体积参数的下降,但两种材料的下降程度存在明显的差异。The material studio molecular simulation analysis software was adopted to predict the free volume parameters of the two kinds of viscoelastic damping materials under static pressure. Prediction results showed that rising of the static pressure would lead to the decrease of the free volume parameters of the two materials,but the free volume parameters had decreases of various degree.
