# Industrial Specification: Drill Frame

## 1. Technical Definition
The structural framework that supports and aligns the drilling components of a Horizontal Directional Drilling Rig.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-250 kN axial load, 0-150 kN lateral load, -20°C to 80°C operating temperature**. Failure boundary: **Material yield strength exceeded at 275 MPa stress concentration at weld joints, 0.5° permanent angular deflection from alignment axis**, Mechanism: **High-cycle fatigue failure due to cyclic bending stresses exceeding S-N curve endurance limit of ASTM A572 Grade 50 steel (207 MPa at 10^7 cycles), compounded by stress corrosion cracking in chloride environments above 50 ppm concentration**.

### 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.
