Dynamic vibration analysis is essential in understanding how composite beam structures behave under various loading conditions, especially when subjected to random harmonic excitations. These excitations can arise from machinery, environmental influences, or operational disturbances, and they can significantly impact structural integrity if not properly understood and mitigated.
In this article, finite element simulation is applied to model composite beams and evaluate their dynamic response. By analyzing modal properties, frequency response functions, and stress distributions, engineers can identify potential weaknesses and optimize the beam configuration. Parameters such as fiber orientation, layer thickness, and boundary conditions are examined to determine their influence on vibration characteristics.
The study also discusses optimization strategies aimed at improving vibration resistance. Techniques include material tailoring, damping enhancement, and structural modification to reduce resonance effects. These approaches help engineers design safer, more durable composite structures suitable for aerospace, automotive, civil engineering, and industrial applications.
Overall, the use of finite element methods provides a powerful tool for predicting vibration behavior and enhancing the performance of composite systems under dynamic loading.
