Design optimization of lightweight Lower Control Arm using finite element method
The Mattingley Publishing Co. Inc., 2020Co-Authors: Rosdi Daud, S H Tomadi, Almor A. A., Mas Ayu Hassan, M. Safwan, A. ShahAbstract:The Lower Control Arm (LCA) is one of the important components in suspension system. The main function of the LCA is to manage the motion of the wheels and hold the wheels to go up and down when hitting bumps. In general, most of the Control Arm made from steel. Although it has higher strength properties but the weight of it can be found excessively heavy in automotive industry without any changes to its design. Light weight and high strength characteristic in the replacement of materials has become the mainstream method in the automotive industry since the weight of the vehicle will affected fuel consumption. In this article, the CAD Models were prepared using Solidworks Software & finite element analysis using ANSYS software. The main significance of the analysis is to determine the optimal design among the three models of LCA that have been designed by comparing the maximum Von Misses Stress, total deformation and safety factor. The FEA results show that the proposed design (third design) of LCA can be considered as an optimum design due to lowest maximum Von Misses Stress, total deformation and safety factor, 96.407 Mpa, 1.116E-8 mm and 1.0373 respectively In additional, the comparison based on the weight and material cost of aluminum and Polyetherether ketone (PEEK) LCA using optimal design also was made. The comparison result shows that the production of LCA using the PEEK material is cheaper and lighter than aluminium material which reduced the weight of LCA up to 67% and 21% reduced in term of material cost

Prediction of Fatigue Failure Location on Lower Control Arm Using Finite Element Analysis (Stress Life Method)
Advances in Material Sciences and Engineering, 2019Co-Authors: S. K. Abu Bakar, Rosdi Daud, H. Mas Ayu, M. S. Salwani, A. ShahAbstract:Analyzing a structure early in the design cycle gives an automotive industry a huge advantage which can reduce development time and cost. Before a prototype can be built and tested, determination of the critical region of the structure should be achieved and thus the design can be improved. The method involves the study of the fatigue failure location and structural integrity of the Lower Control Arm subjected to the load applied mimicking real condition of the Lower Control Arm operation. The 3D geometry of finite element model is simulated in Autodesk Mechanical Simulation. The finite element analysis (FEA) results are compared to critical distance approach whereby prediction of the fatigue failure is focused on critical location of curve near bushing. Finally, it is concluded that this approach can be considered as an initial process for the design of the high life Lower suspension Arm.

design and analysis of lightweight polyetheretherketone peek front Lower Control Arm
AIP Conference Proceedings, 2019Co-Authors: F T Pawi, Rosdi Daud, M. S. Salwani, Mas H Ayu, Tedi Kurniawan, S H Tomadi, A. ShahAbstract:Forged Aluminum is regarded as the optimum process for producing light weight front Lower Control Arm (FLCA) with assured internal qualities and high reliabilities since aluminum forging provides the highest weight reduction effect, as much as 35 to 40% reduction compared to cast iron. However due to the high cost of aluminum and motivation to reduce carbon dioxide emissions, the aim of this research is to develop lightweight material with optimum design of FLCA and achieve equivalent structural performance and function at a reduced cost relative to the baseline forged aluminum FLCA. In this research, the first stage was started with reverse engineering (RE) of forged aluminum FLCA, which RE refers to the process of obtaining a CAD model from an existing physical part. CAD model is prepared using solidwork software and finite element analysis by using Autodesk mechanical simulation software. We constructed a 3D CAD model for both baseline forged aluminum front Lower Control Arm (FLCA) and improved design of FCLA using Solidwork (optimum design). The models are subjected to loading and boundary conditions and then analyzed using the FEA techniques which the optimum design FLCA used the lightweight polymer, polyetheretherketone (PEEK). The structural analysis was conducted to find out the stress, deformation and safety factor of PEEK FLCA. The structural analysis result of PEEK FLCA showed that the standard load given was not exceeded the yield strength of PEEK material, 100Mpa. The safety factor for the optimum design of PEEK FLCA, 1.09 is also bigger than 1. Thus, it showed that it is safe to use lightweight plastic, PEEK as a FLCA to replace forged aluminum and proof that the research aim to develop lighter weight than aluminum is achieved.

Optimization on Lower Control Arm of McPherson suspension based on OptiStruct
Computer-Aided Engineering, 2012Co-Authors: Li ChengAbstract:As to the optimization of Lower Control Arm of McPherson suspension including mass lightening and stiffness improvement,based on topology optimization theory and finite element method,topology optimization is performed on the Lower Control Arm of a casting McPherson suspension by OptiStruct.The optimal material distribution in the required volume is achieved with maximum stiffness.CAD model is rebuilt after optimization,and then the stiffness and modal are compared with those of the original Arm.The results show that the optimization can lighten the mass and enhance the stiffness of Lower Control Arm.
