# Industrial Specification: Bed Frame

## 1. Technical Definition
The rigid structural base of a bed or die that provides support and stability for the working components.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-1500 N/m² distributed load, 0-2.5 mm deflection under load**. Failure boundary: **Yield strength exceeded at 250 MPa stress concentration at weld joints, permanent deformation &gt;5 mm deflection**, Mechanism: **Stress concentration at welded joints exceeding material yield strength (ASTM A36 steel: σ_y=250 MPa) due to cyclic loading fatigue and improper load distribution**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Cyclic loading at 1-5 Hz frequency exceeding 1000 N point loads | 8 | Fatigue crack propagation from weld toe initiating at stress concentration factor K_t=3.2 | Redesign with gusset plates at joints to reduce K_t to 1.5, implement shot peening on weld surfaces to induce compressive residual stresses of -300 MPa |
| Corrosive environment with chloride concentration &gt;500 ppm at 25°C | 8 | Stress corrosion cracking initiating at micro-cracks in heat-affected zone with crack growth rate &gt;10⁻⁹ m/s | Apply zinc-rich epoxy coating (DFT 150 μm) with cathodic protection at -0.85 V vs. Cu/CuSO₄, specify ASTM A588 weathering steel alternative |
