# Industrial Specification: Trencher

## 1. Technical Definition
A heavy-duty construction machine designed to excavate trenches in soil for installing pipelines, cables, drainage systems, or other underground utilities.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-2.5 MPa hydraulic pressure, 15-40 kN·m torque at digging chain**. Failure boundary: **Hydraulic pressure exceeding 3.2 MPa causes seal extrusion, digging chain torque exceeding 55 kN·m causes sprocket tooth shear**, Mechanism: **Seal extrusion failure occurs when hydraulic pressure exceeds the yield strength of nitrile rubber (21 MPa) combined with clearance gap pressure amplification (15:1 ratio). Sprocket failure follows τ_max = 0.577σ_y per von Mises criterion, with 4140 steel having σ_y = 415 MPa**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.
