TESTING APPARATUS FOR EVALUATING FUEL FLOWING SOUND IN FUEL TANK

摘要

The present invention relates to a testing apparatus for evaluating the fuel flowing sound in a fuel tank. A servo motor (23) generating driving force is installed outside an anechoic room (1). A driving bed (12) mounted with a fuel tank (13) is moved by a driving belt (15) generating comparatively less noise. A clutch (26) is disconnected and a brake (27) is operated when the driving bed (12) mounted with the fuel tank (13) is moved along a guide rail (11). Therefore, the testing apparatus for evaluating a fuel flowing sound in a fuel tank can get a test data value for fuel flowing sound in an inertial operation braking mode.
