Crane Hook Structural & Vibrational Analysis (Capstone)

This capstone project evaluated the structural integrity and vibrational behavior of a crane hook designed for construction and lifting applications. The hook was modeled in SolidWorks using realistic dimensions and alloy steel material properties to simulate an industrial component. The study aimed to assess both static load performance and dynamic vibration response.

A static finite element analysis was conducted by applying a 10 kN downward force while fixing the threaded section of the hook. Stress, displacement, and strain distributions were evaluated to determine whether the hook remained within safe operating limits. Results showed that stresses and deformations were well below failure thresholds, indicating adequate structural performance under the applied load.

In addition to static analysis, a frequency study was performed to identify natural vibration modes and resonance-prone frequencies. Five mode shapes were analyzed to understand deformation behavior under dynamic conditions. Hand calculations were used to approximate stress and displacement values, and differences between analytical and simulation results were discussed in terms of modeling assumptions and safety margins.

This project demonstrates the application of combined static and dynamic analysis to safety-critical components, emphasizing fatigue prevention, resonance avoidance, and structural reliability in construction and industrial equipment design.
