# Industrial Specification: Lift Actuator

## 1. Technical Definition
A mechanical or electro-mechanical device that converts energy into linear motion to raise or lower a lift platform.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-20.0 MPa hydraulic pressure, 0-100°C ambient temperature, 0.1-2.0 m/s linear velocity**. Failure boundary: **Hydraulic pressure exceeding 25.0 MPa causes seal extrusion, piston rod deflection exceeding 0.5 mm/m length violates Euler buckling criterion, temperature exceeding 120°C degrades hydraulic fluid viscosity below 32 cSt**, Mechanism: **Seal failure occurs via extrusion when pressure differential exceeds seal material's yield strength (EPDM: 15 MPa, Polyurethane: 25 MPa). Piston rod buckling follows Euler's formula: F_critical = (π²EI)/(kL)² where E=210 GPa (steel), I=πd⁴/64. Hydraulic fluid thermal degradation follows Arrhenius equation with activation energy 85 kJ/mol for mineral oil.**.
