EMG thruster EB1250-60

detailed description:

EMG thruster EB1250-60The braking process of a disc brake is an energy conversion process, in which the kinetic energy of the mechanical system is converted into frictional heat energy. Some of the heat is dissipated into the air, while the majority of the remaining heat is absorbed by the brake, which can cause an increase in the temperature of the brake friction pair. Excessive temperature rise can cause changes in the physical and chemical properties of friction materials, resulting in thermal degradation of braking performance. Thus it can be seen,EMG thruster EB1250-60The change in braking temperature has a significant impact on braking performance. According to whether the temperature sensor is in contact with the brake component, the detection methods of brake temperature can be divided into direct method and indirect method. The direct method is contact temperature measurement, which involves contacting the temperature measuring element with the friction pair element; The indirect rule is non-contact temperature measurement, which means that the temperature measuring element does not directly contact the friction pair element. The direct method can be divided into pre embedding method and pre embedding method. The preset method is to place temperature measuring elements on the surface of the friction pair components to achieve the purpose of picking up temperature signals. This method is commonly used in friction test benches or friction testing machines, where thermocouples are pre-set on the surface of the friction disc to pick up the average temperature of the friction disc surface. The testing position is clear and will not interfere with the temperature field. The pre embedding method involves embedding temperature measuring elements in the friction pair components to capture the friction temperature rise signal. This method can measure the volume temperature, but the arrangement of measuring points is usually cumbersome, and the error is large when the temperature gradient is large. Therefore, it is generally suitable for friction pair temperature measurement systems composed of materials with stable heat transfer performance. By simulating the braking process of a car on the designed brake inertia test bench, temperature measuring thermocouples were installed inside the brake shoes and brake linings to detect and analyze the brake temperature.

The basic idea of the indirect method is to indirectly calculate the temperature of the friction pair by detecting the temperature related to the braking temperature. The implementation of this method requires the help of heat transfer equations and relevant theories of heat conduction. The indirect method is mainly used in situations where the temperature measurement space is limited by structure or materials, and in working conditions where the temperature measuring element cannot be directly installed on the friction pair. By using temperature sensors to detect the ambient temperature of a closed chamber in the braking system, the temperature of the friction plate can be indirectly calculated, and the temperature rise of the friction pair during the braking process can be obtained. The vibration and noise caused by friction during the braking process are also factors that reflect the instability of braking performance. Moreover, vibration and noise can seriously affect the driving safety, comfort, and environmental protection of traffic vehicles. Currently,EMG thruster EB1250-60The analysis and processing methods for vibration signals caused by friction mainly include time-domain method, frequency-domain method, and time-frequency method.
