Abstract

This study investigates the application of second-order differential equations in the modelling and simulation of engineering systems, with a mass–spring system adopted as a representative case study for vibration-based design problems. The aim is to demonstrate how analytical and numerical approaches can be integrated to accurately predict system dynamics and support engineering design decisions. The governing equations are derived from Newton’s second law and solved analytically using characteristic equation methods, while numerical solutions are obtained using the fourth-order Runge–Kutta technique. Key system parameters, including mass, damping coefficient, and spring stiffness, are defined and used to simulate system response under dynamic conditions. The results show strong agreement between analytical and numerical solutions, validating the accuracy of the computational approach. Furthermore, the simulations reveal that system performance is highly sensitive to damping and stiffness variations, which directly influence oscillation amplitude, settling time, and stability. The findings demonstrate that second-order differential equation models provide a robust framework for predicting system behaviour and optimizing engineering design. It is concluded that integrating modelling and simulation techniques into computer-aided design (CAD) environments can significantly enhance design efficiency and performance evaluation. The study recommends the incorporation of advanced simulation-driven tools and intelligent control strategies to further improve the reliability and adaptability of engineering systems.
