Detailed explanation of 18kg rail models and parameters
18kg rails refer to rails with a mass of about 18kg per unit length. They are usually used in railways and rail transit systems and are key components to ensure the smooth and safe operation of trains. Below we will discuss the models and parameters of 18kg rails in detail.
The models of 18kg rails usually vary according to their use, cross-sectional shape and size. At present, the common 18kg rail models mainly include the following:
* Standard type: used for general railway transportation systems, with high load-bearing capacity and stability, is a common model in railway construction.
* Light rail type: lighter than the standard type, suitable for light rail or urban rail transit systems to reduce pressure and impact on urban roads.
The specific parameters of these models include rail height, bottom width, head width, etc. For example, the typical dimensions of a standard 18kg rail are: rail height of about 73mm, bottom width of about 150mm, and head width of about 70mm. These dimensions can be adjusted according to the actual application scenarios to meet different needs and design specifications.
For the 18kg/m rail dimensions, we can learn more about them from the following aspects:
* Rail height: The height of the rail usually refers to the distance from its upper surface to the bottom of the rail. In 18kg/m rails, the rail height is generally between 70-80mm, and such a design can ensure that it has good load-bearing capacity and stability.
* Rail head width: The rail head width refers to the width of the top of the rail. In 18kg/m rails, the rail head width is approximately between 60-80mm to ensure good contact with the wheel and provide a stable support surface.
* Rail bottom width: The rail bottom width refers to the width of the bottom of the rail. For 18kg/m rails, the rail bottom width is generally not less than 120mm to provide a larger contact area, reduce pressure, and prevent the track from sinking.
These dimensions are set in accordance with the International Union of Railways (UIC) and other industry standards to ensure the safety and interoperability of rail systems.
