“…Based on the mesh metric spectrum, a minimum value between 0 and 0.25 is considered excellent for a suitable mesh, while 0.80-0.94 is acceptable. Anything above 1.00 is deemed unacceptable [17]. After the 1.25 mm and 2.5 mm mesh sizes were generated, it was observed that their mesh metric value was 1.25, which exceeded the acceptable threshold of 1 for model analysis.…”

The steering knuckle is a crucial component of student racing vehicles, designed by the Formula Society of Automotive Engineers (FSAE). Developing a lightweight (LW) vehicle that meets the requirements of the student formula car presents a challenge. This study presents a LW design of the steering knuckle using the Topology Optimization (TO) approach for the Formula Society of Automotive Engineers (FSAE) competition considering two different mass constraints (40% and 48%). Moreover, the research includes Stress–Life (SN) curves for three materials, structural steel, 4130 steel, and AISI 1020 steel, providing essential insights into the fatigue characteristics of the model. The results compare the three materials and two mass reduction levels, with steel 4130 achieving a significant mass reduction of 42.70%. Additionally, steel 4130 exhibits superior performance in weight reduction, stress, deformation, and safety aspects. The optimized design meets the criteria for strength, stiffness, and safety under various conditions. The fatigue analysis reveals that AISI 1020 and steel 4130 have superior endurance (1 × 105 and 2 × 105 cycles, respectively). This research provides significant contributions to the development of a LW, high-performance steering knuckle for student formula racing vehicles, highlighting the significance of TO and material selection in achieving optimal outcomes.

“…Producing a mesh that meets the criteria is an acquisition in engineering simulation science that is engineered because computers solve problems based on formulas and various glass and mathematical equations through mesh forms, therefore, the more regular, uniform, and smaller the resulting mesh, the computer will process data with available, but the simulation process that is run also takes a longer time. Both Figures 3 show the average recommended quality of the mesh spectrum according to Ansys experts based on the Skewness and Orthogonal Quality mesh criteria [13].…”

One of the optimization techniques that can be carried out by an engineer in designing a vehicle chassis is to reduce the weight of the chassis itself while still considering several performance targets that must be met, especially in terms of vehicle safety. In this article the author uses the Finite Element Method (FEM) to determine the strength of a component that plays an important role in determining vehicle safety, namely the Rear Axle Suspension Bracket using Ansys and Inventor to create a 3D model of the component, then the author compares the 2 bracket models with the type of material and thickness which was made to find out the stress of the material. One of the parameters that the author uses in determining the Design safety of the two bracket models is the Factor of Safety, Deformation, and Equivalent Elastic Stress values. The results that the authors get showed that the value of the Factor of Safety of bracket Model 1 with the same material as the bracket Model 2, that is 6 mm thick plate is 1.48 or still within the value required by PT. INKA is 1.4 to 1.8 and for the Equivalent Elastic Stress value of 166 MPa or still below the maximum value limit for SS400 material, which is 250 MPa.

“…In general, the skewness should be below 0.95 and results show that the maximum skewness is very good, and the average skewness is excellent, according to the skewness mesh metric spectrum. [61][62][63] As boundary conditions, while fixed support is attached against translation and rotation at one end of the model, axial force and support against rotation are applied at the other end. The governing equations used in FEA are given in Equations ( 1)-( 10).…”

In this study, the behavior of pure glass fiber/epoxy, pure carbon fiber/epoxy, interply hybrid, and locally nested intraply hybrid composites under tensile load was investigated. The specimens were produced by the vacuum‐assisted resin transfer molding (VARTM) method. Interply hybrid composites showed approximately the average tensile strength of the glass and carbon fiber/epoxy composites, with 603 MPa. Intraply hybrid composites had 17% lower tensile strength than pure glass fiber/epoxy composites due to the discontinuity of the fibers in the structure. Therefore, pure or interply hybrid composites are suitable in cases where tensile strength is more important, while in special cases where different properties are desired in different regions of a monolithic structure, locally nested intraply hybrid composites can be used. While the finite element analysis (FEA) results of pure and interply hybrid composites were very close to the tensile test, the amount of deviation increased in intraply hybrid composites due to fiber discontinuity. Fiber and void volume fractions of hybrid specimens were found to be around 62% and 1.45%, respectively. The numerical and experimental results of pure carbon fiber/epoxy composite are validated by the analytical solution.
