The mounting brackets are meant for supporting the structural component and electronic components such as batteries, seats, cabin, chassis, rear body and also it should support the external load such as passenger’s weight. In the ini tial stage the bracket is designed according to the specifications of the mountings without considering any other factors. Analysis is performed for Existing and New modified designs. The design structure is optimized for its topology and topography. In the present work an attempt has been made to produce optimized design of a mounting bracket. The modeling is carried out in CATIA and meshing with quality is ensured through Hyper Mesh. The analysis is carried out using ANSYS by the objective function as shape and topology and the weighting function as weight, and constraints are on deflection and stresses induced.

Four mounting brackets are used to support the entire cabin assembly. Total weight of the cabin assembly is 510 kg including three passengers. Two brackets are positioned at the front side of the cabin and remaining two are positioned at the rear side. In this Project work static and dynamic analysis of the bracket was carried out. In the static analysis only the weight of the cabin including passenger’s weight was considered. In dynamic analysis vertical load, cornering load and acceleration load with some time period were considered. Balamurugan [1] used finite element simulation method with beam and shell elements for modeling of military-tracked vehicle. An Eigen value analysis has been done to estimate natural modes of vibration of the vehicle. The dynamics response of certain salient location is obtained by carrying out a transient dynamic analysis using implicit new marl beta method. Curtis .F. Vail [2], this paper illustrates the use of F.E.Methods for modeling automotive structure for their dynamic characteristics. The results obtained using F.E.Computer models were within 10% of test results. Data reparation typical F.E.Model, outline of the analysis and the display of the data in movie form is covered. Dr. Pawlowski [3] suggestions from his book Body Construction and Design Engineering has been used in this paper for designing the floor. J.L.Hedges, C.C.Norville, O.Gurdogan[4], in these paper coarse and refined idealizations of the structure was analyzed by considering the effect of manufacturing tolerances. Stresses wee predicted under bending and torsion loads. Predictions follows the measured deflection curve but and sensitive to the idealization of the beam. Karuppaiah [5] has done vibration analysis of a light passenger vehicle using a half-car rigid model and a finite element model. It has found that the results from the rigid body model are slightly in the lower side as compared to those from finite element model. Parametric study has also been carried out to study the effect of different parameters on vibration levels in the vehicle. The advantages and disadvantages of the non-contact method for road profile measurement have also been brought out. Karuppaiah [6] applied finite element method for model and vibration/stresses analysis of a passenger vehicle. The block lancozs method has been successfully used for the model analysis. The experiments were carried out using piezo-electric accelerometers and strain gauges to measure the vibration and strain gauges to measure the vibration and strain levels at critical points of vehicle. The prediction values through F.E.M were match well with experimental result. And also he has been carried out with a view to find the optimum suspension/tyre characteristics for maximum ride comfort in the vehicle. Kiyoshi Miki [7]. This paper presents the outline of a theoretical analysis of bending and torsional vibration of passenger car bodies. Body structure is simulated by a framework with tension rigs and additional panel stiffness’s. The framework is a three-dimensional model for the bending and torsional vibration, or two- dimensional for the bending vibration, and is analyzed by the lumped mass system. All input data are calculated from drawings, and therefore characteristics of body structure are forecast and controlled in the design process.
