In order to solve the technical problem of high temperature vibration characteristics testing of metal bellows, a low-cost and continuously adjustable temperature test system for metal bellows was developed. The test system uses the arc-shaped quartz lamp array as the radiation heating device and uses LabVIEW to accurately control the temperature of bellows. Axial and radial external excitation is applied to the metal bellows through an electromagnetic exciter, the vibration response signal is obtained by the dynamic acceleration sensor, and the data collector is used for real-time collection and storage to obtain the bellows vibration response. Taking the DN108 stainless steel bellows as the test sample to test its frequency response curve at different temperatures. The test proves that the system can obtain the high temperature vibration characteristics of the bellows stably and reliably.
