“…There are dual approaches of model updating which are direct method and sensitivity method [19]. Model updating will be performed as an optimization technique and being presented by the structural optimization capability [24][25][26][27]. Several updating parameters which are Young's modulus and Poisson ratio for both materials were considered to be included in model updating procedure.…”

Abstract. Friction stir welding (FSW) of aluminium and magnesium alloys face high demands in automotive and aerospace application due to its advanced and lightweight properties. FSW is an emerging solid state joining process in which the material that is being welded does not melt and recast. The main objectives of this project are to perform model updating based on finite element analysis (FEA) and experimental modal analysis (EMA) of dissimilar material of aluminium alloy AL 7075 and magnesium alloy AZ 31B. Modal properties such as natural frequencies, mode shapes are obtained and compared between FEA and EMA. The discrepancies of first five modes natural frequencies are below than 10% and the model updating have been conducted to minimize the error between two methods. This model updating are based on sensitivity analysis in order to make sure which parameters are given more influence in this structural dynamic analysis. Young's modulus and Poisson's ratio both materials are selected in the model updating process. After perform model updating, total average error of the natural frequencies of dissimilar friction stir welding plate is improved significantly.

“…The value of You ng's modulus was allowed to vary from 1.549 GPa to 2.184 GPa for plate of 5% kenaf composition, 1.69 GPa to 2.184 GPa for plate of 10% kenaf composition, and 1.79 GPa to 2.184 GPa for plate of 15% kenaf composition which are the range value of the composite material with the tested composition [17]. At the same time, the thickness value was allowed to vary in small range from its initial presumes value since the thickness of the composite plate can hardly diverse much all over the plate structure due to its slight unevenness on lower surface.In addition, by performing the sensitivity analysis [18][19][20] [18][19][20] on the selected parameters, the actual properties of the composite structure can be computed and the presumed value of the composite was corrected. Table 3 shows the changes of the updated parameter properties from their initial values.…”

“…For example, Esfandiari [13] in his study has demonstrated the utilization on frequency response function (FRF) in model updating aside from using the extracted modal data (natural frequencies, damping ratios and mode shapes) from the FRF obtained experimentally. On the other hand, in another study of model updating procedure explain the practice of making adjustment using modal data [14][15][16][17][18]. Although the above investigation examined the various approach of model updating, to the best of author's knowledge, there are quite a number of references in the literature systematically describe the procedure of model updating on composite structure focusing on natural fibre.…”

Abstract. Model updating is a process of making adjustment of certain parameters of finite element model in order to reduce discrepancy between analytical predictions of finite element (FE) and experimental results. Finite element model updating is considered as an important field of study as practical application of finite element method often shows discrepancy to the test result. The aim of this research is to perform model updating procedure on a composite structure as well as trying improving the presumed geometrical and material properties of tested composite structure in finite element prediction. The composite structure concerned in this study is a plate of reinforced kenaf fiber with epoxy. Modal properties (natural frequency, mode shapes, and damping ratio) of the kenaf fiber structure will be determined using both experimental modal analysis (EMA) and finite element analysis (FEA). In EMA, modal testing will be carried out using impact hammer test while normal mode analysis using FEA will be carried out using MSC. Nastran/Patran software. Correlation of the data will be carried out before optimizing the data from FEA. Several parameters will be considered and selected for the model updating procedure.a Corresponding

Chassis frame is the skeleton of an automobile industry. It must be hard to resist the adequate shock, twist, vibration and bending stress occurred in operating condition. The material selection and design of chassis frame plays vital role in automobile industry. The chassis can resist the total load acting on the system and it holds the entire body of an automobile. So, highest stress, most equilateral stress and deflection are considerable factors while design of the chassis. In this Paper stainless steel, epoxy and aluminum are the different material used for chassis frame and it is modeled using solid works software and the Finite element analysis has been carried out with using ANSYS. The chassis frame has been optimized based on the most shear stress, equivalent stress and deflection and also responsiveness inspection is carry through to minimize the weight.
