Investigation of Equivalent Alternating Stress and Damage in Arm Type Rotating Flywheel

Rakesh, Somvir Arya, Subodh Siwach

Abstract :

Flywheels have many causes of their failure. Among them, Equivalent Alternating Stress, Damage, maximum tensile and bending stresses induced in the rim and tensile stresses induced in the arm under the action of centrifugal forces. Due to these causes there is a definite Equivalent Alternating Stress and Damage of the flywheel. In this paper by using finite element method, evaluation of Equivalent Alternating Stress and Damage of flywheel are studied. For FE analysis the models of flywheel having four, six and eight no. arms are developed. For different cases of loading applied on the flywheel and the minimum Equivalent Alternating Stress and Damage are determined by using ANSYS. From this analysis it is found that as the No. of arms increases Equivalent Alternating Stress and Damage both decreases.
