Method and test bench for investigating vibrations, for acoustic investigations and/or functional examinations of transmission gears

摘要

A gearbox (2) vibration, acoustic and functional test procedure excites gearbox shafts (20) in vibration using an electromagnetic, hydraulic or pneumatic actuator (10) working over a small angle at a neutral position or a combustion engine mounted in a frame (12) and records the rotational frequency and amplitude response as a function of the excitation : Includes INDEPENDENT Claims for a test stand using the procedures.
