Action step decomposition
1. Put the sample to be tested into the fixture.

2. The R-axis rotates the sample under the suction cup of the drop frame, The β axis rotates according to the angle required for the drop test.

3. The suction cup drops to absorb the sample, θ The shaft rotates according to the angle required for the drop test.

Operation Interface Overview
Software Features:
- After each test, the drop speed (m/s) is calculated and displayed automatically.
- Three vacuum suction cups can be switched freely using the electric control system.
- After each drop, the system automatically resets to the original suction position.
- Both drop height and suction height can be set manually. The drop count is also displayed and can be reset as needed.
- A built-in safety door protection feature ensures that the machine operates only when the door is securely closed.

Dropping speed meter (actual speed is in accordance with that captured by high speed camera or laser seismograph):
| Point Verified (mm) | Standard Speed (m/s) | Indication Speed (m/s) | Average Value | Error of Indication |
|---|
| 1 | 2 | 3 | 4 | 5 |
