# Industrial Specification: Target Mounting Assembly

## 1. Technical Definition
A mechanical assembly designed to securely mount and position verification targets within an Isocenter Verification System.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-500 NÂ·m torque, 0-100 Î¼m positional tolerance, -20Â°C to 80Â°C temperature**. Failure boundary: **Exceeding 550 NÂ·m torque causes permanent deformation, positional error &gt;150 Î¼m exceeds optical verification system resolution, temperature &gt;85Â°C induces thermal expansion beyond compensation range**, Mechanism: **Yield strength of 6061-T6 aluminum alloy (276 MPa) exceeded at 550 NÂ·m, thermal expansion coefficient mismatch between aluminum (23.1 Î¼m/mÂ·Â°C) and stainless steel mounting hardware (17.3 Î¼m/mÂ·Â°C) creates stress concentrations**.

### 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.
