# Industrial Specification: Mining Excavator

## 1. Technical Definition
A heavy-duty, high-capacity excavator specifically engineered for surface mining operations to extract minerals, ores, and overburden.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-35 MPa hydraulic pressure, 0.5-2.5 m/s bucket velocity, 85-95°C hydraulic fluid temperature**. Failure boundary: **Hydraulic pressure exceeding 42 MPa causes seal rupture, bucket velocity below 0.3 m/s indicates pump cavitation, hydraulic fluid temperature above 110°C initiates thermal degradation**, Mechanism: **Hydraulic system failure occurs due to Bernoulli's principle causing cavitation at pump suction when NPSHa &lt; NPSHr, and Arrhenius equation-driven thermal degradation of hydraulic fluid at temperatures exceeding 110°C**.

### 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 exceeding ISO 4406 18/16/13 cleanliness level | 8 | Servo valve spool seizure causing loss of bucket control | Installation of 3 μm absolute beta₃≥200 filtration with continuous particle counting |
| Structural resonance at 8.5 Hz matching boom natural frequency | 8 | Fatigue crack initiation at boom-to-stick weldment | Finite element analysis-driven structural redesign with damping ratio ζ≥0.05 and natural frequency shift to 12.5 Hz |
