33-53 DETERMINAREA PE CALE ANALITICĂ A FRECVENȚELOR DE VIBRAȚIE NATURALĂ A UNEI JANTE ȘI CERCETĂRI ALE ASPECTELOR LEGATE DE INFLUENȚA ACESTORA ASUPRA INTEGRITĂȚII STRUCTURII
ANALYTICAL DETERMINATION OF
NATURAL FREQUENCIES VIBRATION OF A RIM AND RESEARCH ON THE ASPECTS OF THEIR INFLUENCE ON THE STRUCTURE INTEGRITY
This scientific and technical paper, outlines the studies made on vibrations aspects in correlation with exploitation of a wheel rim. Rims are critical components of the vehicle wheel. The wheel is a device that enables efficient movement of an object across a surface by rotating itself on that surface. To find the natural frequencies and stiffness a model is designed using commercial software SOLIDWORKS and the factors are estimated by commercial analysis software ANSYS Workbench. The present work deals with analysis of an aluminium alloy wheel rim subjected to vertical load, air pressure, damping factor and stiffness of material under various condition are found(different centrifugal speeds that coresponds to different speeds of vehicle).
