# Industrial Specification: Vibration Table

## 1. Technical Definition
A mechanical platform that generates controlled vibrations to compact sand in mold boxes during the sand molding process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 mm amplitude at 50-100 Hz frequency, 0.5-2.0 m/s² acceleration**. Failure boundary: **Exceeding 4.0 mm amplitude at 120 Hz or continuous operation above 3.5 m/s² acceleration for &gt;30 minutes**, Mechanism: **Resonance-induced structural fatigue at natural frequency (typically 80-110 Hz for steel frames) causing crack propagation at stress concentrations exceeding yield strength (250 MPa for mild steel)**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.
