# Industrial Specification: Quick Coupler

## 1. Technical Definition
Hydraulic attachment interface enabling rapid tool changes on tracked loaders

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-35 MPa (150-350 bar)**. Failure boundary: **42 MPa (420 bar) burst pressure, 0.5 mm radial deformation at 38 MPa**, Mechanism: **Plastic deformation of hardened steel (AISI 4140) due to hoop stress exceeding yield strength (σ_y = 690 MPa) at 42 MPa internal pressure, calculated via Lamé equations for thick-walled cylinders**.

### 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.
