1. The primary purpose of calibration is to ensure the accuracy and reliability of force and torque measurements obtained from sensors (primarily strain gauges) mounted on the wheelset. 2. Challenges and ObjectivesWheelset calibration presents challenges due to the complex geometry and multi-axial loads (vertical, lateral, and longitudinal forces).3.The primary stage where known loads are applied to the stationary wheelset to derive the Calibration Matrix (a set of coefficients for converting strain signals to forces) through regression analysis.4.This calibration system is the foundation for collecting high-quality data, which helps engineers make data-driven decisions.
