# Industrial Specification: Digging Assembly

## 1. Technical Definition
The core digging mechanism of a trencher that excavates soil and creates trenches.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-35 bar hydraulic pressure, 50-150 RPM rotational speed, 0.5-2.5 m/s linear excavation speed**. Failure boundary: **Hydraulic pressure exceeding 45 bar causes seal rupture, rotational speed exceeding 180 RPM induces centrifugal force &gt; 15g leading to bearing failure, soil resistance &gt; 2.8 MPa causes structural deformation**, Mechanism: **Hydraulic seal failure due to elastomer fatigue at pressure cycles &gt; 10^6, bearing failure from Hertzian contact stress exceeding 1.5 GPa, structural yielding at von Mises stress &gt; 250 MPa**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Hydraulic fluid contamination with particulate &gt; 15 μm | 8 | Cylinder scoring and seal degradation causing pressure loss &gt; 20% | Install 10 μm absolute filtration with differential pressure monitoring at 0.3 bar threshold |
| Soil abrasion coefficient &gt; 0.8 with silica content &gt; 60% | 8 | Cutting edge wear rate &gt; 0.5 mm/hour leading to excavation efficiency drop below 70% | Apply tungsten carbide hardfacing with Vickers hardness &gt; 1200 HV and implement ultrasonic thickness monitoring |
