# Industrial Specification: Tire Pressure Control System

## 1. Technical Definition
A system that monitors and regulates tire pressure in pneumatic tire rollers to ensure optimal compaction performance and safety.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2.0-8.0 bar**. Failure boundary: **1.5 bar (underinflation) / 9.0 bar (overinflation)**, Mechanism: **Rubber hysteresis loss exceeding 15% at underinflation reduces compaction efficiency; tire carcass ply separation occurs at overinflation due to tensile stress exceeding 25 MPa in nylon reinforcement cords**.

### 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.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Pressure sensor diaphragm fatigue from 10^6+ compression cycles at 5 Hz operating frequency | 8 | Sensor drift exceeding ±0.2 bar accuracy specification | Diaphragm thickness optimization to 0.5 mm 316L stainless steel with shot peening surface treatment |
| Solenoid valve coil insulation breakdown at 85°C ambient temperature | 8 | Valve stuck open causing continuous pressure loss at 0.3 bar/min | Class H insulation (180°C rating) with epoxy encapsulation and thermal derating to 70% duty cycle |
