Ensuring Robustness Against Vibration Loads
Knorr-Bremse introduced the ACR System to improve the efficiency and durability of commercial vehicle disc brakes by reducing residual drag torque. This innovation minimizes fuel consumption and brake pad wear, extending the lifespan of braking systems. However, to ensure long-term reliability, it was essential to optimize the ACR’s design to withstand harsh vibration loads encountered during real-world operation.
Strain Measurement and Statistical Analysis
Using HBK strain gauges, vibration loads were applied to the ACR under different design conditions. Fatigue life predictions were performed with nCode GlyphWorks, and the resulting data formed the foundation for a statistical root cause analysis, identifying the critical design factors that would maximize the system’s durability under vibration loading.
