In this paper, numerical analyses of the disc heating process during braking were conducted. An analysis was performed on the influence of the brake pad pressure value p on the disc and the angular velocity ω on the value and distribution of temperature fields, as well as the influence of heat generated due to braking on the stress intensity state in the disc. All analyses were carried out using the Finite Element Method. For the analyzed cases, applications were developed in the APDL language within the system. The rapidly increasing number of vehicles is causing a deterioration in road safety conditions. The technical condition of vehicles has a direct impact on the safety of their use. An element responsible for active safety in road traffic is the braking system, whose main task is to reduce driving speed or stop the vehicle at a specific location. Furthermore, the braking system is expected to ensure the shortest possible braking distance, the shortest possible system reaction time, and that braking capacity remains constant even during prolonged braking, while maintaining maximum vehicle stability.
The two most popular braking systems are drum and disc brakes. Disc brakes dissipate heat better and are therefore more effective, however, the fundamental problem, i.e. (…)
