# Industrial Specification: Operator Cab

## 1. Technical Definition
Enclosed compartment on a hydraulic excavator that houses the operator and controls.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-1.5 m/s² vibration amplitude at 5-100 Hz frequency range**. Failure boundary: **Structural failure occurs at sustained vibration exceeding 2.5 m/s² RMS at resonant frequencies between 15-35 Hz**, Mechanism: **Resonant fatigue failure due to structural resonance with excavator's hydraulic system pulsation at 25 Hz ± 10 Hz, amplified by cab mounting bracket natural frequency of 28 Hz**.

### 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.
