Railway Brake System Thermal Analysis

This test applies thermal analysis methods to evaluate the temperature behavior and heat dissipation performance of railway brake systems under various braking scenarios. The test measures brake pad, disc, and caliper temperatures during simulated service and emergency braking to ensure systems operate within safe thermal limits and do not experience brake fade or mechanical degradation. Excessive temperatures can compromise braking performance and component integrity, posing serious safety risks. Brake component manufacturers, rolling stock designers, and certification bodies require accredited thermal testing to validate brake system designs. ISO 17025 accreditation ensures consistent, traceable thermal measurement and validates compliance with European railway safety standards.

What it measures

  • Peak and transient brake temperature profiles
  • Temperature distribution across brake components
  • Heat dissipation rates and thermal time constants
  • Brake fade characteristics and recovery behavior
  • Thermal cycling endurance and material stability
