Steps
- Design a scaled shock strut with a spring and damper and 3D print the mounts.
- Build the drop rig on the linear rail with calibration weights.
- Mount the IMU and program the Arduino to log impact acceleration.
- Drop from fixed heights and measure peak G.
- Try different spring and damper combos to reduce peak G.
- Compare results to your analysis and document them for your portfolio.
