Design of an engine test bench for vibrations practical courses

Abstract

The aim of the training period is to design and implement a test bench for use during practical courses in vibrations at ENSMM. This bench includes an electric motor, and a set of rotors that are linked to the drive shaft through a transmission. This transmission will be modular and allow the use of elastic or rigid components (gearbox). The modular sys.tem will illustrate various vibration problems: balancing rotors, structural modifications, fault detection and dynamic absorber. CAD tools will be used for the design of the system, according to the required specifications. Separte elements will then be acquired or manufactured if necessary, in particular for elements with defects that will be used in the system. The final assembly will be made and tests will be conducted for validation purpose.
