Mitigating structural resonance through frequency-tuned passive damping

Experimental validation of passive vibration control systems using a variable-stiffness oscillating tower and custom Python telemetry.

Problem Space

Modern skyscrapers are susceptible to wind and seismic oscillations that compromise structural integrity. The objective was to empirically validate the physics of a Tuned Mass Damper (TMD) using a simplified Single Degree of Freedom (SDOF) model.

Solution Architecture

Constructed a flexible testing rig with an adjustable pendulum damper. Developed a custom DAQ system using an MPU-6050 accelerometer and Arduino to stream real-time vibration data to a Python dashboard for Fast Fourier Transform (FFT) analysis.

System Highlights

Real-time signal processing pipeline using Python (SciPy/Matplotlib)
Logarithmic decrement analysis to quantify energy dissipation efficiency
Frequency domain identification (FFT) of structural natural modes
Hardware integration of MEMS accelerometers with serial telemetry
