人造多晶冰的动力学参数试验研究
|
摘要
基于低温动三轴试验,研究人造多晶冰在轨道交通分级循环荷载作用下的本构关系与动力学参数指标。在不同负温、频率条件下,考察试件轴向动应力–应变关系曲线,获得冰的动力本构关系可以用线性黏弹性模型描述;动弹性模量随着温度的升高而降低,随频率增大而增大;黏性系数随着温度的升高而增大,随频率增大而减小的结论;并合理解释了温度、频率对冰的动力学参数指标的影响机理。
Based on the dynamic tri-axial tests at low temperature,the dynamic constitutive model and its parameters of artificial polycrystalline ice are studied under stepped axial cyclic loading.It is concluded that the dynamic constitutive relation of ice can be fitted by use of the linear viscoelastic model through the experiments under various temperatures and frequencies.Dynamic elastic modulus decreases with the rise of temperature,and increases with the rising frequency.Viscosity coefficient increases with the increasing temperature,and declines with the increase of frequency.Furthermore,the influences of temperature and frequency on the dynamic parameters of ice are interpreted rationally.
