Tightness test stand for vehicles, has test chamber with automatic guided acoustic detection sensors, where sound pressure amounts emerging at leakage point are audible and are analyzed with leak localization aids

摘要

The tightness test stand has a test chamber with automatic guided acoustic detection sensors and acting on a vehicle mounted on a lift frame. The acoustic detection sensors, particularly shotgun microphones are rotatably mounted in all directions at the top of a device, particularly at the tip of a robot arm (4). The sound pressure amounts emerging at the leakage point are audible and are analyzed with leak localization aids. The leakage point-location is connected with the coordinate-guided sampling function, so that sound pressure amounts are audible.
