Název v původním jazyce

Signals detection by sensors and determination of friction coefficient during brake lining movement

Popis výsledku v původním jazyce

The article presents a laboratory device by which the course of two signals can be detected and recorded by measuring, using two sensors - strain gauges and the DEWESoft DS-NET measuring apparatus. The first sensor can be used to obtain the time course of the tensile force in the threaded rod connecting the two levers of the shoe brake, on which the brake shoes are mounted on the pivot. The second sensor detects the torque of the rotating parts system. The friction coefficient of the brake lining on the circumference of the rotating brake disc shell can be calculated from the known values measured by the sensors, the design dimensions of the brake, and the revolutions of the rotating parts system. The measured values of friction coefficient during brake lining movement, woven asbestos-free material Beral 1126 containing brass fibers and resin additives, when rotating at known speeds of the brake drum, show a slightly higher value than the measured values of friction coefficient with uniformly delayed rotation of the brake drum. The methodology for determining the friction coefficient of the brake lining allows the laboratory device to verify its magnitude for different friction materials under different operating conditions.
