Railway Wheelset Equivalent Conicity Measurement

This test method defines procedures for determining the equivalent conicity of railway wheelsets, a critical geometric parameter that affects vehicle stability, curving behavior, and wear characteristics. Equivalent conicity influences hunting oscillations, lateral forces, and noise generation during operation. The measurement is essential for railway manufacturers, maintainers, and operators to ensure safe and economical wheelset performance across different track geometries. Accreditation ensures consistent, reproducible measurements that support compliance with European interoperability standards and informed maintenance decisions.

What it measures

  • Equivalent conicity value of wheelset profiles
  • Wheel profile geometry and wear patterns
  • Contact angle and friction coefficient relationships
  • Stability margin and hunting potential
  • Comparative conicity values for different operating conditions
