“…A loaddeformation database containing the relationship between the load situation and deformation of the crane hook was created using numerical computation. Upon completion of the study, it was found that the load in the damaged hook was located between the end point and the lowest point, and its direction was towards gravity [4]. In a study predicting the dimensions of the hook for various section topologies while preserving depth and cross-sectional area, it was concluded that the trapezoidal section had the least stress [5].…”

Topology optimization is the process of optimizing the shape and material distribution of a part. This study examines the topology optimization of the hanging apparatus of a boat's crane. The goal here is to design a lighter and more efficient hanging apparatus. Initially, topology optimization was performed using a CAD software such as Autodesk Fusion 360. This software aids engineers in creating complex designs, simulating real-world scenarios, and optimizing material distribution. The design process began with the use of a non-equilateral triangle to determine the shape of the part. Later, two cylindrical rings that attach to the pole were added. These steps completed the initial geometry. Subsequently, it was indicated that the part needed to be light and resistant to weather conditions. Therefore, aluminum 6061 material was chosen. The material properties were chosen to ensure the proper functioning of the part. A static analysis was performed to determine the strength of the part. The forces and constraints applied to the part were simulated considering a one-ton capacity. A displacement of 1.32 millimeters and a safety factor of 6 were found. Then, following the topology optimization, an analysis of the new geometry resulted in a displacement of approximately 4 millimeters for the part. The predetermined minimum safety factor is 3, and the factor found in the analysis was 3.7. This is an acceptable value to ensure the structural integrity and safety of the part. The optimization process aimed to reduce the mass of the part. By preserving the initially determined safety factor, savings were made in the material and a successful reduction of approximately 42% in mass was achieved. This study demonstrates that topology optimization is a significant tool in engineering design and CAD software such as Autodesk Fusion 360 can be effectively used in this process. The analyses and optimizations conducted reveal that it's possible to design a lighter and more efficient hanging apparatus. This provides numerous advantages such as cost savings, performance increase, and reduction of environmental impact.

Laminated hooks are widely used in steel industry. Due to its high load carrying capacity they are use for loading and unloading of material in heavy steel industry. Laminated hook got its name from the process of manufacturing it. they are made of plates which are rivets together. In industry when continuous and unloading occur the failure of hook take place, but in laminated hook when crack or faults occurs the faulty plate can replace by the new one this reduces time and cost. In this project we will calculate the bending stress occurred in hook and the factures effecting its life Weight optimization of hook using topological approach it's taken in to consideration. Topological approach of weight optimization, in this weight will be reduce in area where more stress is present. Simulation of the hook is done using topological approach. model is created, then meshing is done, FEA analysis(ANSYS 14.0) carried out. The geometry which will obtain at the end of the simulation, the dimension will be consider and scaled prototype is manufacture. Testing of the laminated hook is done on UTM.
