Experimental Techniques for Rotor Performance Measurements 850078

Rapid application of automotive brakes causes high temperatures with resulting thermal gradients in brake rotors. To analyze these components accurately, the inputs and heat transfer coefficients must be known. Transient thermal patterns measured on prototype parts were recorded on video tape using an infrared scanner. These surface temperature values give accurate temperatures and gradients which can be used as inputs for subsequent analysis methods. A pressure sensitive paper was also used to measure the pressure distribution on the rotor caused by flexibility in the rotor caliper, and mounting system.
