Evaluation and Development of Engine Components and Accessories With Electrodynamic Shakers

Abstract

The electrodynamic shaker is a useful tool in the evaluation and development of engine components and accessories. As the shaker vibratory input to the component fixture or the engine assembly is controlled, the vibratory response of the component or accessory can be determined. A brief review of vibration theory and vibration response of several simple mechanical elements is included. Three examples of the development of engine components by use of fatigue fixtures and three examples of evaluation of engine mounted accessories are presented.
