During the braking process many undesirable effects can appear that can disturb the safety of all participants in the traffic. It can be considered that using the new alternative friction materials is the key to improve the performance of brake system and reduce the negative effect on the environment. In this research paper, the temperatures and the stresses that appeared during the braking process will be investigated deeply. Different materials for braking disc [cast iron, aluminum matrix composites (AMC), and carbon-ceramics materials (CCM)] were used to achieve the numerical analysis. Finite element analysis (transient structural) was applied to obtain the numerical results. The results showed that the lowest temperature appeared during the heavy-duty braking process when using aluminum matrix composites, while the highest temperature appeared during the braking process when using different types of material for disc brake (cast iron and CCM). Also, the lowest stresses appeared during the braking process when using carbon-ceramics material. This study presents the criterion to select optimal material for braking discs based on the developed approach.

使用替代材料研究制动系统的热性能

在制动过程中，可能会出现许多不良影响，这些不良影响会干扰交通中所有参与者的安全。可以认为使用新的替代摩擦材料是提高制动系统性能并减少对环境的负面影响的关键。在本文中，将对制动过程中出现的温度和应力进行深入研究。使用不同的制动盘材料[铸铁，铝基复合材料（AMC）和碳陶瓷材料（CCM）]进行数值分析。应用有限元分析（瞬态结构）获得数值结果。结果表明，采用铝基复合材料时，在重载制动过程中出现最低温度，当使用不同类型的材料进行盘式制动（铸铁和CCM）时，在制动过程中会出现最高温度。同样，当使用碳陶瓷材料时，在制动过程中出现的应力最小。这项研究提出了基于改进方法为制动盘选择最佳材料的标准。
