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。
Aiming at the need of thermal-vibration joint environment test for aircraft structure working in high-temperature superposition vibration environment, a non-contact thermal vibration joint environmental test technology based on laser measurement is studied. Based on this technology, a set of thermal vibration joint environment Test system Test a test piece, the system includes vibration test system and heating test system two independent parallel subsystems. The experimental results show that the combined heat and vibration testing system based on non-contact thermal shock and environmental testing technology can accurately simulate the actual heating process of the test piece while providing the vibration environment required for the test piece, value.
