摘要	Monitor and control unit is essential to almost all of the modern aircrafts or spacecrafts which always places in a relatively closed space and requires a compatible mechanical environment to ensure its normal function. The acoustic vibration and thermal loads developed in the operation of the aircraft determine a complex environment for its monitor and control unit. In particular there should be couple effect among the thermal vibration and acoustic responses. This article presents numerical simulation studies on a thermo-acoustic-vibration response of a typical thin-walled box to reveal the multi-physics environment of the monitor and control unit. The thermo-structural equations were proposed and solved numerically following that the vibro-acoustic analysis was implemented. The coupled algorithm was developed to simulate the structure response and sound distribution and predict the acoustic loss during transmitting through the box shell. The validation cases of the vibration and acoustic response of a plate were performed at first. The outcome provides the multi-physics environment prediction method for designing and optimizing the monitor and control unit.
