Solution Brief

Acoustic qualification testing for space hardware

At the system level of assembly, most spacecraft are required to be acoustically tested.

Acoustic testing at lower levels is typically reserved for large, low-surface-density components and subsystems, such as solar arrays, antennas and reflectors. Acoustic loads can cause paint flaking, debonding and cracking of built-up structures, and electronic failures in equipment mounted on honeycomb panels. Using Simcenter Testlab software solutions provide state-of-the-art test methods to replicate such loads, either using a reverberant acoustic field or loudspeakers in ordinary (acoustic) rooms to mimic the loads – a technique known as direct-field acoustic noise (DFAN).
