摘要
本文针对ＺＮ－１和ＺＮ－２粘弹性材料，通过大量试验，首先定量探讨了其力学性能随环境温度、激振频率、变形幅疽和滞回圈数等因素的变化情况；随后，就风振控制问题，考察了长时间荷载作用下，材料内部的温升平衡情况；最后，在文献［１］的基础上，利用试验数据确定了刻画材料力学性能的四参数模型的有关参数。
Bascd on test results, the effect of environment temperature, exciting frequency, strain magnitude and hysteretic time on the mechanical properties of ZN-1 and ZN-2 visoelastic materials has been quantitatively discussed. The temperature improving pro- cesses of ZN-1 and ZN-2 during a short and long period of exciting are propcised. The model parameters of the four-parameter model have been determdned for ZN-1 and ZN-2 respectively.
