Abstract

Satellite structures inside a fairing experience severe high-level random acoustic loads during launch phase. In order to confirm that satellite structures and equipment withstand the launch environment, ground acoustic testing is conducted in the process of design. Satellite is exposed to the diffused sound field in a large reverberant room during ground acoustic tests. Besides, a satellite is exposed to the standing wave sound field, which is called 'Fill Effect', inside a fairing during launch. This paper discusses the difference between the vibration responses induced by the diffused sound field and those induced by the standing wave sound field.
