Shape optimization of wheeled excavator lower chassis

Özbayramoğlu, Erkal
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 using genetic algorithm, is modified and embedded in the designed program.


Development of bolted flange design tool based on finite element analysis and artificial neural network
Yıldırım, Alper; Kayran, Altan; Department of Aerospace Engineering (2015)
In bolted flange connections, commonly utilized in aircraft engine designs, structural integrity and minimization of the weight are achieved by the optimum combination of the design parameters utilizing the outcome of many structural analyses. Bolt size, number of bolts, bolt locations, casing thickness, flange thickness, bolt preload, and axial external force are some of the critical design parameters in bolted flange connections. Theoretical analysis and finite element analysis (FEA) are two main approach...
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...

ÖZTÜRK, VEYSEL YALIN; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2014-08-28)
An optimization study is performed target being the reduction of dynamic transmission error (DTE) for a selected operational range, where the operating torque and speed ranges are defined. For this purpose, two different models, i.e. a single degree of freedom (SDOF) lumped gear dynamics model and a multi-degree of freedom (MDOF) lumped model of a gear pair which is combined with shaft and bearing dynamics are employed. The differences between the optimization results obtained through loaded static transmis...
Aero-structural design and analysis of a joined-wing kit
Alanbay, Berkan; Şahin, Melin; Department of Aerospace Engineering (2015)
In this study, a multi-objective aero-structural multidisciplinary design optimization (MDO) of a joined-wing kit which is installed on a transonic free fall munition is performed. The main purpose of the joined-wing kit is to enable the munitions to extend their range and gain standoff attack capability. In order to fulfill these aims joined-wing kit configurations are generally investigated through various analyses. Each joined-wing configurations are determined through two geometric key parameters namely...
Shape optimization of an excavator boom by using genetic algorithm
Uzer, Cevdet Can; Söylemez, Eres; Department of Mechanical Engineering (2008)
This study concerns with the automated structural optimization of an excavator boom. The need for this work arises due to the fact that the preparation of the CAD model, performing finite element analysis and model data evaluation are time consuming processes and require experienced man power. The previously developed software OptiBOOM, which generates a CAD model using a finite set of parameters and then performs a finite element analysis by using a commercial program has been modified. The model parameter...
