# Industrial Specification: Locking/Latching System

## 1. Technical Definition
Mechanical system that secures an insulated chamber door in a closed position to maintain environmental seals.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 kN latch force, 0.1-0.3 mm door-seal compression, -40°C to 85°C ambient temperature**. Failure boundary: **Latch force &lt; 0.4 kN causes seal leakage &gt; 0.5 L/min at 50 Pa pressure differential, actuator torque &gt; 3.5 N·m causes gear tooth shear stress &gt; 250 MPa**, Mechanism: **Hooke's law elastic limit exceeded in spring components at &gt;0.4% strain, Hertzian contact stress &gt; 1.1 GPa causes surface pitting in cam mechanisms, thermal expansion mismatch (Δα=12×10⁻⁶ K⁻¹) between stainless steel and aluminum creates binding at &gt;70°C ΔT**.

### 2.1 Analytical Physics Model
Governed by the **Frame Structural Deflection Analysis**:

> **Primary Equation**: $\delta = \frac{5 q L^4}{384 E I}$  
> **Engineering Impact**: Ensures structural stability for multi-stage machines.
