# Industrial Specification: Lifter Actuator

## 1. Technical Definition
A mechanical or electromechanical device that provides controlled lifting motion within a separation mechanism.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-20.0 MPa hydraulic pressure, 0-150 mm stroke length, -40°C to +120°C ambient temperature**. Failure boundary: **Hydraulic pressure exceeding 25.0 MPa causes seal extrusion, piston rod deflection exceeding 0.15 mm/m induces bending fatigue, temperature surpassing 150°C degrades hydraulic fluid viscosity below 10 cSt**, Mechanism: **Seal extrusion failure occurs when hydraulic pressure exceeds the seal material's yield strength (typically 15-25 MPa for polyurethane), causing plastic deformation and leakage. Bending fatigue initiates microcracks at stress concentrations when alternating stresses exceed the endurance limit of AISI 4140 steel (approximately 400 MPa). Thermal degradation follows the Arrhenius equation where fluid oxidation rate doubles per 10°C temperature increase above 100°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.
