Mechanical Test Engineer · Space Systems
I’m Vishal Joshi, a mechanical test engineer working on space hardware. I combine vibration testing and instrumentation with Python analysis to understand structural response.
From signal interpretation to repeatable data review. Independent studies covering structural dynamics, signal analysis, test-data automation and vibration-test evaluation.
Structural dynamics
Connect beam theory, numerical eigenmodes and synthetic modal correlation in a reproducible cantilever study.
Result First three finite-element frequencies agree with beam theory within 0.0017%.
Signal analysis
Recover known frequency components from a synthetic accelerometer signal and examine the effect of filtering.
Result Three imposed components recovered at 42.11, 117.19 and 310.06 Hz; largest reported difference 0.19 Hz.
Test-data automation
Turn a multi-channel measurement CSV into a consistent, repeatable first-pass engineering review.
Result 12 input-validation cases passed: one valid CSV accepted and 11 invalid variants rejected.
Test evaluation
Evaluate synthetic test-input tracking, compare resonance searches and examine multi-channel control.
Result Command level 7.614 g RMS; controlled level 7.703 g RMS. Three resonance modes compared.
