Experimental Studies of Vibration Characteristic and Mechanical Parameters of Al-alloy Plate at Low Temperatures

TuZhihua;Zhang Zhong; Zhao Lizhong;Zhang Peiqiang  
In this paper,the vibrational characterisitc of Al-alloy plate at low temperatures is studied bythe experimental strain modal analysis meth-od.Some mechanical parameters such as dynamic Young's moduli E,shear-moduli G and Possion's ratio γ are drawn out from the modal parameters which are identified by system identification techniques in the time do-main,and it shows that the mechanical parameters value of Al-alloy vary with the temperature.
