2. Study of vibration on tensioner of transmition by belts / Estudo de vibrações em auto-tensionador de transmissão por correias
This investigation describes a method, which permits evaluating the best parameters, in the study of tensioner project system in its transversal vibration control and actuating forces. The construtive and operating parameters, as: geometry, inertia, tensioner spring stiffness, belt stiffness, and operating conditions as: excitation frequencies, estatic and d
