How to determine the required quantity of Rubber Rail Pads?
To determine the required quantity of rubber rail pads, you must first calculate the number of pads per rail using the track layout, then multiply that number by the total number of rails. Additionally, you must account for factors like train weight, speed, and environmental conditions to select the correct pad specifications, and always refer to the rail fastening system manufacturer's specifications for precise guidance.
| Rubber Rail Pad | ||
| Technical Parameter | Unit | Value |
| Stiffness | KN | 90-130 |
| Hardness Shore A | ℃ | 72-80 degree |
| Electronic Resistance | Ω | ≥ 106 |
| Tensile Strength before Aging | Mpa | ≥12.5 |
| Elongation before Aging | % | ≥250 |
1. Calculate the number of pads per rail
- Count pads per rail: Determine the number of rail pads needed for a single section of track based on your specific layout and the fastening system's design.
- Multiply by total rails: A standard track has two rails. If the fastening system requires a pad for each sleeper, and you have sleepers per rail, you will need pads, plus any extra pads for special sections.
2. Select the correct pad specifications
- Consider train weight and speed: Heavier and faster trains require more durable pads that can withstand higher loads.
- Check fastening system specifications: Always refer to the manufacturer's specifications for the correct thickness, material, and load capacity to ensure compatibility with other components like baseplates and clips.
- Choose the right material: The material choice depends on the application. For example, a high-speed railway may need a natural rubber pad, while a system carrying heavy loads might require a composite material.
3. Finalize the quantity
- Add a buffer: It is wise to add a small percentage (e.g., 5-10%) to your final count to account for waste, damage, or future maintenance needs.
- Order the correct quantity: Based on your calculations, order the exact quantity needed, plus the buffer amount.
