Experimental and numerical tests of thermo-mechanical processes occurring on brake pad lining surfaces

摘要

One of the most important systems in cars and trucks are brakes. The braking temperature on a lining surface can rise above 500°C. This shows how lining requirements are so strict and, what is more, continuously rising. Besides experimental tests, a very supportive method for investigating processes which occur on the brake pad linings are numerical analyses. This paper presents the results of laboratory brake lining tests in the special test rig, called IL-68. Furthermore, based on this testing machine, the numerical model was developed. In the final stage computations done using a dynamic code called LS-Dyna were compared with laboratory tests.
