# Industrial Specification: Debris Hopper

## 1. Technical Definition
A container component on a road sweeper that collects and temporarily stores debris during sweeping operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-500 kg load capacity, 0-60°C ambient temperature, 0-100% relative humidity**. Failure boundary: **Structural failure occurs at 750 kg static load or 550 kg dynamic load, material fatigue failure at 10⁶ stress cycles at 400 MPa stress amplitude**, Mechanism: **Yield strength exceedance of ASTM A36 steel (250 MPa) under overload conditions, stress concentration at weld joints exceeding fatigue limit (206 MPa at 10⁶ cycles)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Corrosive chloride ion concentration exceeding 150 ppm in collected debris | 8 | Pitting corrosion penetration rate exceeding 0.5 mm/year at weld seams | 316L stainless steel cladding (3 mm thickness) with cathodic protection at -850 mV vs. Ag/AgCl reference |
| Cyclic loading at 5-10 Hz frequency from road vibration during sweeping operations | 8 | Fatigue crack initiation at stress concentration factor Kt=3.2 locations after 2×10⁵ cycles | Finite element analysis-optimized fillet radii (R≥15 mm) and shot peening to induce 400 MPa compressive residual stress |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in debris hoppers for road sweepers?
**A**: Debris hoppers are constructed from high-strength steel and abrasion-resistant steel plates to withstand heavy loads and abrasive materials during sweeping operations.

### Q: How does the hydraulic dump cylinder function in a debris hopper?
**A**: The hydraulic dump cylinder allows for controlled tipping of the hopper to empty collected debris efficiently, typically operated from the vehicle cab for convenience and safety.

### Q: What maintenance is required for road sweeper debris hoppers?
**A**: Regular inspection of the hopper body for wear, checking hydraulic connections, ensuring drainage systems are clear, and monitoring intake chute alignment are essential maintenance tasks.

## 6. Manufacturing Compliance
- ISO 9001:2015 - QUALITY MANAGEMENT SYSTEMS
