Measuring the wheel profile accurately is crucial for railway safety and maintenance. The complete wheel profile is measured using specialized equipment.
Utilizing Laser Sheet of Light Sensors
Based on the provided information, the complete wheel profile is measured by means of two OPTImess 2D laser sheet of light sensors. This method employs advanced laser technology to capture precise dimensions of the wheel's surface.
Here's a breakdown of how these sensors work together:
- Sensor One: One sensor is positioned to measure the inside flat surface of the wheel. It captures the profile data extending up to the very top of the wheel flange. This is the part of the wheel facing the vehicle center.
- Sensor Two: The second sensor is dedicated to measuring the side of the wheel profile facing the rail. This includes the tread area and the outer face of the flange, which are critical contact points with the track.
By combining the data from these two sensors, a comprehensive and accurate digital representation of the wheel's entire profile is obtained. This allows for detailed analysis of wear patterns, flange height, tread hollowing, and other critical profile characteristics.
