Pneumatic tire is one of the rather complex motor vehicle components. Stress-strain relationship of rubber is highly nonlinear and rubber is nearly incompressible. The reinforcement in form of textile or steel cords which have very high elastic muduli compared to rubber and the microbuckling of the cords in rubber matrix makes the analysis difficult. Frictional contact with ground and rim, asymmetric loading, and large displacements and strains under normal service conditions are further sources of complication. With the development of digital computers and finite element codes, it is now possible to model the tires more precisely. Static finite element tire models having different levels of complexity are presented in this study. In all models, the reinforcing textile and/or steel plies and microbuckling, frictional contact, and large displacements are included. In some of the models, nonlinear stress-strain relationship of rubber is also included. Results obtained from the models are validated by experiments and compared with the available results in literature.

Finite element analysis of cornering characteristics of rotating tires
Erşahin, Mehmet Akif; Ünlüsoy, Yavuz Samim; Department of Mechanical Engineering (2003)
A finite element model is developed to obtain the cornering force characteristics for rotating pneumatic tires which combines accuracy together with substantially reduced computational effort. For cord reinforced rubber sections such as the body plies and breaker belts, continuum elements with orthotropic material properties are used to improve solution times. Drastic reductions in computational effort are then obtained by replacing the continuum elements with truss elements which do not require orientation...
Prediction of automobile tire cornering force characteristics by finite element modeling and analysis
Tönük, Ergin; Ünlüsoy, Yavuz Samim (2001-05-01)
In this study, a detailed finite element model of a radial automobile tire is constructed for the prediction of cornering force characteristics during the design stage. The nonlinear stress-strain relationship of rubber as well as a linear elastic approximation, reinforcement, large displacements, and frictional ground contact are modeled. Validity of various simplifications is checked. The cornering force characteristics obtained by the finite element tire model are verified on the experimental setup const...
Shape optimization of wheeled excavator lower chassis
Özbayramoğlu, Erkal; Söylemez, Eres; Department of Mechanical Engineering (2008)
The aim of this study is to perform the shape optimization of the lower chassis of the wheeled excavator. A computer program is designed to generate parametric Finite Element Analysis (FEA) of the structure by using the commercial program, MSC. Marc-Mentat. The model parameters are generated in the Microsoft Excel platform and the analysis data is collected by the Python based computer codes. The previously developed software Smart Designer [5], which performs the shape optimization of an excavator boom by ...
Structural crashworthiness analysis of a ladder frame chassis subjected to full frontal and pole side impacts
Dagdeviren, Semih; Yavuz, Mecit; Kocabas, M. Ozan; Unsal, Eren; Esat, Volkan (Informa UK Limited, 2016-01-01)
Automobile chassis is a major element of structural crashworthiness in road motor vehicles. Various chassis geometry and topology research studies have been conducted to improve crash energy absorption characteristics of the chassis. In side impacts, crashworthiness of an automobile body depends not only on the chassis geometry and topology, but also on the design and reliability of other structural members such as B-pillar and side panels. This study aims to contribute to the investigations on the effects ...
MODELING OF DYNAMIC DELAMINATION IN L-SHAPED COMPOSITE BRACKETS
Gozluklu, Burak; Çöker, Demirkan (2012-11-15)
One of the widely used geometrically complex parts in recent civil passenger aircrafts is the L-shaped composite brackets connecting ribs to skins. Due to the sharp curved geometry, interlaminar opening stresses are induced and delamination occurs under considerable mode-mixities at the corner. Dynamic phenomena during delamination initiation and propagation of L-shaped beams are investigated using dynamic (explicit) finite element analysis in conjunction with cohesive zone methods (CZM). In ABAQUS a sequen...
