| 摘 要： | 针对工作在高温叠加振动环境中的飞行器结构进行热振联合环境试验的需要,研究了一种基于激光测量的非接触式热振联合环境试验技术,并基于该技术搭建了一套热振联合环境试验系统对某试验件进行试验,该系统包括振动试验系统和加热试验系统两个独立并行的子系统。试验结果表明,基于非接触式热振联合环境试验技术的热振联合环境试验系统在提供试验件所需振动环境的同时,可以精确地模拟试验件实际使用中的加热过程,具有较好的实用价值。

| Abstract: | 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. |
