In this study, topology optimization of a jet engine bracket which was proposed from GE Aviation challenge for improving the brackets is presented using finite element analysis (FEA). The minimum mass, maximum equivalent stress and first natural frequency are selected for the objective functions to topology optimization. Then, topology optimization procedure is implemented according to the identified boundary conditions and objective functions. Finally, the manufacturing model is obtained and compared with the original model according to the maximum equivalent stress, mass reduction and first natural frequency. Also, modal analysis and static analysis results of the proposed models are presented. ARTICLE HISTORY

“…Since different structures are required for tow hooks depending on the condition of the chassis or the lower part of the monocoque body and the spare wheel, production is made according to the vehicle model [1,2]. When the studies in the literature related to the subject are examined: carried out a study on the design improvements of the connection brackets, in which the suspension elements are mounted on the body, especially in the chassis areas of commercial vehicles [3]. In the proposed bracket designs; The gist is to reduce the weight and increase the strength of the parts.…”

In this study, a new design has been developed for towing hook dies used in hot forging processes. For this objective, analysis studies were carried out with different process parameters and methods for new designs in dies for both hot forging process and product. After the analysis, the die designs were determined that produced the prototype products at the optimum speed, efficiency and quality. While designing a special die for hot forging operation, a new die design has been developed in which both processes can be performed using a single die with two stages, pre-shape and final shape. Compared to the dies studied for hook groups in the literature and our old dies currently being worked, it is aimed to eliminate the errors caused by the inability to calibrate the final shape such as early wear, short die life, burr residue formation. Such a technics specific to the part as specific to the towing hook was performed for the first time, and with the die design developed by comparing the results of analysis studies, field trials and prototype studies in the Q-Form simulation program, the production of towing hook at optimum efficiency was achieved.

“…The stresses resulting from these forces should be considered in the design process of the engine mount bracket. Moreover, the material of an engine mounting bracket should have proper strength and rigidity, high vibration absorption and damping ratio, high durability against alternating forces, and suitable NVH 1 properties (Chang 2006). Also, the mechanical properties of the material are strongly affected by the manufacturing process of the material.…”

“…It was concluded that the maximum Green-Lagrange strain and the maximum strain energy density can be used as two suitable criteria in fatigue analysis of the engine mounting bracket. Chang (2006) optimized the shape and topology of an engine mounting bracket and reduced its weight by 24.2%. Pan et al (2007) improved the stiffness and strength of an engine mounting bracket up to 50% and decreased its weight by 12% through redesigning the shape and topology of the part.…”

The engine mounting bracket is one of the most sensitive parts of an automobile that is used to connect the engine to the body of the vehicle. Under operating conditions, it is subjected to static, cyclic, and exceptional loads. Since this part is generally manufactured by the casting method, the casting-induced defects can affect its service life. In this study, an engine mounting bracket was first subjected to an experimental static load test, the results of which showed the absence of defects. The endurance limit was then measured experimentally using the high-cycle fatigue test. According to the results of the staircase-Locati fatigue test, the relative mean resistance load was obtained as 1.24 with a relative scatter of 0.07 which fell in the unsafe operating region of the engine mounting bracket. Therefore, a finite element analysis was conducted to determine the critical regions on the part and modify its geometric shape to improve its performance. The crack onset and growth regions obtained in the fatigue tests agreed well with the critical areas identified in the finite element analysis. After modifying the geometric shape and eliminating production defects, several experimental tests were performed to evaluate the endurance limit. The results showed that an increase of only 0.9% in the mass of the engine mounting bracket, decreased stress concentration up to 37%. The relative mean resistance load was increased up to 1.33 with a relative scatter of 0.06, which provided safe performance in the vehicle operating condition. Finally, the modified bracket passed the dynamic load test without any crack and loosening of the screws during the assembly process.
