# Industrial Specification: Safety Frame

## 1. Technical Definition
A structural component of a rotating cab that provides protection and containment for operators and equipment.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150 kN static load, 0-50 kN dynamic load at 0-15 Hz vibration frequency**. Failure boundary: **Material yield strength exceeded at 180 kN static load or 60 kN dynamic load at 15 Hz**, Mechanism: **High-cycle fatigue failure due to stress concentration at weld joints exceeding S-N curve endurance limit of 250 MPa for structural steel**.

### 2.1 Analytical Physics Model
Governed by the **Frame Structural Deflection Analysis**:

> **Primary Equation**: $\delta = \frac{5 q L^4}{384 E I}$  
> **Engineering Impact**: Ensures structural stability for multi-stage machines.
