Friction pair tests or model brake tests are one of the trials done in order to evaluate friction pair materials usefulness in full-scale brakes. Such tests are both time consuming and expensive, so most of the manufacturers want to reduce them as much as possible by using numerical simulations for both time and costs savings. It is not possible to eliminate laboratory tests entirely because of the safety regulations requirements. Without regulatory compliance, no brake material can be used in consumer products such as cars or airplanes. Nowadays most of the FEM programs are capable of simulate braking (friction) process in many of its aspects. Accuracy of calculations varies according to complexity of the model and phenomena taken into account. One of the interesting aspects of braking is the friction temperature generation especially due to its destructive impact on the vehicle brakes. Laboratory evaluation of the temperature can be performed in limited spectrum because of inaccessibility of the friction area. FEM calculations can help to determine temperature changes and temperature value during process. It also helps to determine temperature induced damaging conditions for the friction material or the whole brake design. In this paper author compares FEM of friction temperature calculations and laboratory test performed in Landing Gear Laboratory of Institute of Aviation in Warsaw where author works on daily basis. FEM simulation was created in order to resemble mentioned friction material test and to create model of the geometry of the tested material including test stand parts. All of the calculations were performed using COMSOL MULTIPHISICS software.
