Flexible disk coupling numerical analysis model method

Abstract

Flexible disk coupling is an equipment to translate the force of rotation without alignments. It consists of body, disk and bolt-nut. The characteristics of flexible disk coupling such as transfer torque, rotating speed, weight and etc. are decided by the shape and the number of disk. Also, the contact condition between each disk is most effective factor to the characteristics of flexible disk coupling. In this paper, we focus on developing the vibration analysis and design tool for flexible disk coupling. First, the numerical analysis model is developed and modal analysis is performed by using this numerical model, second, the modal analysis result is compared with impact hammering test result to identified the numerical analysis model. The commercial program, "Ansys Workbench", is used and five cases different contact conditions between each disk supporting from Ansys Workbench is considered in this paper.
