VIBRA3D – An interactive 3D SDOF System animator

Interactive MATLAB tool for visualizing 3D single-degree-of-freedom vibrations with real-time parameter updates.

Overview

VIBRA3D is an interactive MATLAB program developed for educational purposes.

It visualizes the dynamic behavior of a single-degree-of-freedom system in 3D.

Users can adjust mass, stiffness, damping, initial conditions, and excitation parameters, and watch the vibration, displacement-time graph, and resonance curve update in real time.

Key Features

- Interactive 3D SDOF system visualization

- Real-time parameter modification via mouse scroll wheel

- Displacement-time graph and resonance curve display

- Excitation frequency control to observe resonance effects

- Smooth animation and responsive graphical feedback

Installation & Usage

Add the VIBRA3D folder to the MATLAB path and run `launcher.m`.

Select a model from the dropdown menu, start the animation with the play button and adjust parameters in the input table with mouse scroll wheel.
