Dynamic Modeling and Performance Assessment of a Mechanical Power Take-Off System for Ocean Wave Energy

Wave energy represents one of the most promising renewable sources due to its high energy density and predictable availability compared to wind and solar power. Despite its potential, technological exploitation remains challenging because of harsh marine environments, high installation and maintenance costs, and the absence of a dominant technology. This work presents a comprehensive review of wave energy conversion technologies and provides a detailed kinematic and dynamic analysis of a novel mechanical system designed to transform oscillatory linear motion into continuous unidirectional rotary motion, suitable for electricity generation. Particular focus is placed on the analytical modeling of the system, the design of a flywheel for energy stabilization, and performance evaluation. Results highlight the feasibility of the proposed configuration and its potential advantages compared to conventional hydraulic systems.
