摘要: 通过对不同初始密度的泡沫铝进行准静态压缩和动态冲击试验‚得到了泡沫铝材料在中低应变率下的力学行为.结合分析含多种内变量的粘塑性本构模型的物理意义‚推荐了适合于泡沫铝材料的一维粘塑性本构模型‚并对推荐模型进行了拟合‚拟合结果与实验结果吻合比较好.该模型和实验结果均反映了泡沫铝材料的应变率负敏感特性.

Abstract: Proposed in this paper is a mathematical model of the three-phase induction motor in the three-phase stator
winding ABC frame.In this model‚the variable values of voltage and current are just the true values of those in the
stator winding.This model is of the advantage of non-transformation of voltage or current between the converter and
the stator when applied to the motor control system including converter circuit‚and is of the same superiority as the dq
frame model.A simulation model for this mathematical model was then structured by Matlab/Simulink and was veri -
fied by an example.The results show that the simulation results accord well with the actual values‚which indicates the
validity of the proposed model.

Key words:  aluminum foam, viscous-plastic constitution model, strain rate
