A Numerical Study of Second-Order Differential Equations in Vibration Analysis of Mechanical Systems

Abstract

Differential equations of the second order are the fundamental building blocks of classical mechanical system modelling, notably in the field of vibrational analysis. The scope of this study is comprised of the numerical solutions for second-order ordinary differential equations (ODEs), which are used in mechanical systems with single-degree-of-freedom (SDOF) and multi-degree-of-freedom (MDOF) when they are subjected to dynamic loads. The research mixes numerical computing, vibrational theory, and mathematical modelling in order to analyses the behavior of mechanical components under a variety of damping and stiffness conditions. The data used in the study comes from engineering simulations and general vibrations recordings that have been verified. The findings of this study provide evidence that explicit numerical approaches, such as the Runge-Kutta and Newmark-beta methods, are useful in solving second-order equations for vibrations that have been dampened or not dampened. The establishment of internal consistencies in vibration parameterization is made easier by the use of graphs, numerical examples, code scripts, and comparison charts, which are all used in the theoretical modelling process. It is via the intersection of applied mathematics and mechanical engineering that the operational aspects of how empirically verified solutions reinforce mathematically established physical realities are brought to light at this conference. Not only does this convergence result in an increase in knowledge, but it also provides engineers with a toolset for vibrational diagnostics that is both analytically sound and computationally practical from a computational standpoint.
