Structural Dynamics Visualizer
Education
Free · Designed for iPad. Not verified for macOS.
Explore vibration, mode shapes, resonance, and earthquake response through interactive structural animations and real-time response plots.
Structural Dynamics Visualizer is an interactive educational tool for exploring the behavior of vibrating structural systems.
Visualize free vibration, forced vibration, mode shapes, sinusoidal ground motion, and earthquake response using animated structural models and synchronized response plots.
Explore single-degree-of-freedom and multi-degree-of-freedom systems, including carts, shear frames, cantilevers, and vertical spring-mass systems.
Adjust model parameters such as mass, stiffness, damping, initial displacement, initial velocity, forcing amplitude, forcing period, and number of degrees of freedom, and immediately see how those changes affect structural response.
Features include:
• Free-vibration response and damping behavior
• Forced vibration and resonance visualization
• SDOF and MDOF structural models
• Mode shapes and modal response
• Shear-frame and cantilever systems
• Sinusoidal base excitation
• Earthquake response using recorded ground motion
• Interactive parameter controls
• Animated structural deformation
• Response histories and natural-period visualization
Structural Dynamics is designed as a teaching and learning aid for students studying structural engineering, earthquake engineering, vibrations, engineering mechanics, and related subjects.
