# Industrial Specification: Translation Actuators

## 1. Technical Definition
Mechanical components that provide controlled linear motion within segment erection systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-35 MPa hydraulic pressure, 0-100 mm stroke length, -20°C to 80°C ambient temperature**. Failure boundary: **Hydraulic pressure exceeding 42 MPa causes seal extrusion, stroke length beyond 105 mm induces mechanical binding, temperature above 85°C degrades hydraulic fluid viscosity below 15 cSt**, Mechanism: **Seal extrusion failure occurs when hydraulic pressure exceeds the seal material's yield strength (typically 25 MPa for HNBR), causing plastic deformation and leakage; mechanical binding results from exceeding the actuator's geometric tolerance stack-up (typically ±0.05 mm cumulative tolerance)**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.
