# Industrial Specification: Hydraulic Dump Cylinder

## 1. Technical Definition
A hydraulic cylinder specifically designed to provide the lifting and tilting force for dumping operations in debris handling equipment.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-210 bar**. Failure boundary: **235 bar (yield strength of SAE 1045 steel at 35 HRC)**, Mechanism: **Plastic deformation of cylinder barrel due to hoop stress exceeding material yield strength: σ_h = (P × D)/(2t) where P=235 bar, D=100 mm, t=8 mm**.

### 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 |
| :--- | :--- | :--- | :--- |
| Contaminant ingress (ISO 4406:2017 Class 22/20/18 exceeded) | 8 | Spool valve stiction causing uncontrolled cylinder extension | Integrate 3 μm absolute filtration with differential pressure monitoring at 0.35 bar threshold |
| Piston seal extrusion gap exceeding 0.15 mm at 100°C | 8 | Hydraulic fluid bypass causing 35% efficiency loss | Implement stepped piston design with 0.05 mm maximum radial clearance at operating temperature |
