本文在自行研制的铝合金流变性能测试装置上运用流变学和系统辩识方法,借助微型计算机测试,处理了铝铜合金凝固温度区间的流变参数(剪切模量G,粘滞系数η和屈服极限τ_s)。结果表明,采用这种方法流变参数测试处理的速度快,精度高,并把大量的流变参数估计的计算工作变成了简单的键盘操作。
In this paper, rheological and systematic identification methods were applied to the rheological property test device of aluminum alloy developed by ourselves. With the help of microcomputer test, the rheological parameters of the aluminum-copper alloy in the solidification temperature range (shear modulus G, viscosity coefficient η and yield limit τ_s). The results show that using this method, the rheological parameters testing process is fast and accurate, and a large number of computations of rheological parameters estimation are transformed into simple keyboard operations.
