# Industrial Specification: Actuation Cylinder

## 1. Technical Definition
A hydraulic or pneumatic cylinder that provides the mechanical force to engage or disengage a clutch or brake.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-21 MPa hydraulic, 0.1-1.0 MPa pneumatic**. Failure boundary: **Seal extrusion at 25 MPa hydraulic pressure, rod buckling at 350 MPa compressive stress**, Mechanism: **Seal extrusion due to pressure differential exceeding Shore A 90 durometer nitrile rubber yield strength of 15 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 15 μm particles exceeding ISO 4406 18/16/13 cleanliness level | 8 | Spool valve stiction causing 500 ms response delay | Install 10 μm absolute beta₃=200 filter with differential pressure monitoring |
| Piston rod misalignment exceeding 0.05 mm/m perpendicularity tolerance | 8 | Asymmetric seal wear leading to 0.5 L/min internal leakage at 10 MPa | Implement laser alignment during installation with 0.01 mm/m tolerance verification |
