“…Moreover, the heat quantity converted from the kinetic energy of the braking object should be checked in order to avoid failure of the brakes caused by overheating. Hence, some researches have focused on heat attenuation of materials for braking [6][7][8][9][10][11][12], Grzes, et al [13] developed a model of a disk brake to study the temperature at the discrete contact between two rough surfaces and studied two approaches of calculation of the flash temperature. However, the system dynamic of the braking process was not taken into consideration and the braking impact on the transmission link was not analyzed either.…”

Industrial brakes pose the dilemma of weighing brake capability against brake impact since the brake torque cannot be adjusted. On the one hand, the brake torque may be insufficient to stop the movement within a limited distance or parking position. On the other hand, the brake torque may be so high it can damage the transmission chain. In this study, the traditional brake strategy and the field oriented control (FOC) brake strategy were compared through simulation and a rotational inertia test. The influence of the rated brake torque and the open-closed ratio were obtained. Based on the test and simulation results, a semi-empirical formula that defines the relationship between relative brake capability and open-closed ratio was developed. Additional simulations were performed to analyze the performance of the brake in a flexible transmission chain. As an industrial application example, the benefits and the cost of a 'smart brake' based on the FOC brake strategy were analyzed. The results indicate that the equivalent brake torque with the FOC brake strategy is a function of the realtime controllable input and open-closed ratio, which can be conducted during the braking procedure. This can be an efficient way to solve the above problems.

“…[11][12][13][14] For example, stick-slip oscillation of the Earth's plates can cause serious earthquakes, stick-slip vibration in car brakes can result in irritating noise, stick-slip vibration of a drill string can cause tool failure and so on. [15][16][17][18][19][20] As a kind of non-smooth vibration, stickslip oscillation is a complex nonlinear problem. [21][22][23][24] Usually, stick-slip motion is undesirable and thus should be suppressed or reduced.…”

This work presents an experimental and theoretical combined study of the effects of the elastic rubber blocks with different surface modifications on the friction-induced stick–slip oscillation and wear of a brake pad sample in sliding contact with an automobile brake disc. The experiments are conducted on the customized experimental setup in a pad-on-disc configuration. The experimental results show that (1) the friction system with the plain rubber block still exhibits visible stick–slip oscillation, but the intensity of the stick–slip oscillation is reduced to a certain degree compared with the Original friction system (without rubber block); (2) the grooved rubber blocks display a better ability to reduce the stick–slip oscillation compared with the plain rubber block; (3) the rubber blocks with a vertical groove (perpendicular to the relative velocity) or a horizontal groove (parallel to the relative velocity) or a diagonal groove (45° inclined to the relative velocity) on their surfaces can suppress the stick–slip oscillation more effectively with various degrees of success. The experimental results also reveal the varying effects of the different rubber blocks on wear. To explain the experimental phenomenon reasonably, a theoretical analysis is conducted to investigate the effects of different rubber blocks on both stick–slip oscillation and wear using ABAQUS. Furthermore, the analysis of the contact pressure on the pad interfaces and the deformation of the rubber blocks are studied to provide a possible explanation of the experimental results.
