Thermal Interference

Aluminum has become a widely used material in the automotive industry due to the need for production of lighter automobiles. As the number and complexity of aluminum products increase, it becomes necessary to improve methods used to join these parts. Thermal interference fitting is one of these methods. It is not possible to calculate interference fit stresses accurately for all conditions using traditional calculation methods, and a method to calculate separation frequency of interference fitted aluminum parts is not available. This study investigates elastic–plastic interference fit stresses and separation frequencies of lightweight metal gear and steel shaft interference fitted joints (which have begun to be used widely in designs) using analytical and numerical calculation methods. It was found as a result of the study that plastic deformation occurred due to decreasing diameter, and increasing interference and numerical calculation methods produced accurate results. It was determined as a result of numerical analysis that the separation frequency of lightweight metal gears was lower in smaller interference fit diameters compared with steel gears, and that this increased in connection with increasing interference fit diameter and was found to be higher compared with steel gears.

The present work deals with the computation of surface stresses and deformation in the presence of friction. The evaluation of the elastic-plastic contact is analyzed revealing three distinct stages that range from fully elastic through elastic-plastic to fully plastic contact interface. Several factors of sliding friction model are discussed: surface roughness, mechanical properties and contact load and areas that have strong effect on the friction force. The critical interference that marks the transition from elastic to elastic- plastic and plastic deformation is found out and its connection with plasticity index. A finite element program for determination contact analysis of the assembled details and due to details of deformation that arose a normal and tangencial stress is used.
