Problems solved by technology

[0002] Traditional modal tests are usually carried out in an open environment, but there is thermal convection between the surface of the specimen and the surrounding environment, which affects the thermal modal analysis of the structure to a certain extent. In order to eliminate or reduce the heat loss caused by convection, the design a vacuum box test environment
