Experimental Technology Study for Thermo-Vibration United Environment

To meet the requirements of thermo-vibration united experimental environment for aircraft structure working in such environment,a thermo-vibration united experimental technology was studied based on noncontact laser measuring method.The theory of noncontact laser measuring method is Doppler principle,as shown in formula(1).Based on this technology,a thermo-vibration united experimental system was established.The thermo-vibration united experimental system including two individual subsystems: thermal experimental system shown in Fig.7 and vibration experimental system shown in Fig.8.Experimental results show that this thermo-vibration united experimental system can simulate specimen heating process accurately and provide vibration environment for specimen.
