# Industrial Specification: Ship Unloader

## 1. Technical Definition
A specialized machine used to unload bulk materials from ships at ports and terminals.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 MPa hydraulic pressure, 15-60 RPM rotation speed, -20°C to +50°C ambient temperature**. Failure boundary: **Hydraulic pressure exceeding 3.2 MPa causes seal rupture, rotation speed exceeding 75 RPM induces structural resonance at 12.5 Hz, ambient temperature below -25°C causes hydraulic fluid viscosity to exceed 800 cSt**, Mechanism: **Hydraulic system failure due to Pascal's law pressure transmission exceeding material yield strength (σ_y = 250 MPa for steel components), structural fatigue from resonance at natural frequency matching operational harmonics, thermal contraction differential (α_steel = 12×10^-6/°C vs α_hydraulic_seal = 150×10^-6/°C) causing seal failure**.

### 2.1 Analytical Physics Model
Governed by the **Tractive Power & Resistance Model**:

> **Primary Equation**: $P = \frac{F \cdot v}{\eta}$  
> **Engineering Impact**: Ensures motor torque capacity exceeds operational inertia.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| F | Total Tractive Resistance | Engineering Constant |
| v | Belt Speed | Engineering Constant |
| \eta | Efficiency | 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 with 0.005 mm particulate accumulation | Triple-stage filtration system with 3 μm absolute filters and continuous particle monitoring |
| Gearbox lubrication starvation below 0.8 L/min flow rate at 40°C | 8 | Planetary gear tooth pitting fatigue initiating at 10^7 cycles under 500 N·m torque | Forced lubrication system with redundant pumps and flow sensors triggering shutdown at 0.7 L/min |
