“…When the electromagnetic brake works, the vehicle's kinetic energy is converted into thermal energy to be dissipated. Part of the thermal energy is stored in the brake disc causing the rise of brake disc temperature and another part of the thermal energy is sent out into the air by the constantly rotating brake disc (Artus et al, 2005).…”

Abstract. In this paper, the optimal design and control method of electromagnetic brake for a typical city driving cycle are studied to improve its energy consumption characteristics. The prediction models of the braking performance and power consumption for electromagnetic brake were established, and their accuracies were verified on the hardware of the loop simulation platform. Moreover, the energy consumption based on the ECE-EUDC driving condition was taken as the objective function, and a mathematical model for the optimal design of the electromagnetic brake was established. Genetic Algorithm was used to seek global optimal solution of these design variables on the premise of the given electrical and space constraints. Finally, the effect of thermodynamic properties of electromagnetic brake on the energy consumption characteristics was analyzed, and the energy saving control method of electromagnetic brake was also proposed. Experimental results show that the energy saving optimal design and control that this paper investigates can significantly improve the energy efficiency of electromagnetic brake.

“…Vehicle is also one important part influencing the highway safety and many accidents occur because of or partly because of vehicle aspect. Artus et al (2005) holed the idea that the surface temperatures of the brake discs are closely connected to the braking efficiency and the braking efficiency are closely connected to the highway safety; many traffic accidents occur due to a loss of control on vehicle by the driver and this is mainly due to a loss of friction between tire and road (Ghandour et al, 2010); the vehicle speed is also connected to highway safety, the higher the vehicle speed was, once the accident occurred the more severe the result was, so many highways set speed limit to reduce accidents (Garber et al, 2006;Oh and Mun, 2012). So the vehicle is one aspect we have to consider connected to highway safety.…”

The objective of this study is to establish the mountainous freeway risk degree forecast model. Highway safety, especially mountainous freeway, relates to person, vehicle, road and environment four aspects including many factors. Firstly, this study analyzed some researches about the highway safety from these four aspects respectively. Secondly, this study considered many factors of these four aspects, established the mountainous freeway risk degree forecast model, listed the survey content needed in the forecast model. Finally, this study took Changjin Freeway in Jiangxi Province, China as example, used 91 accident data from January, 2006 to July, 2012, adopted the multiple linear regression method using spss 17.0 to obtain each parameter value of the forecast model and analyzed some parameter values to the mountainous freeway safety. The mountainous freeway risk degree forecast model is necessary and useful to evaluate the risk degree for constructed mountainous freeway, to estimate the safety of unconstructed mountainous freeway and to provide basis to improve mountainous freeway safety.

In the present work, different ventilated disc brake rotor configurations were analyzed to enhance the heat transfer rate and obtain the uniform temperature distribution in the rotor. CFD code used in this work was validated using experimental results obtained by conducting experiments on a test rig. The experimental analysis was performed to calculate the mass flow rate and heat dissipation through the rotor. Further, different types of rotor configurations viz. straight radial vane (SRV), Tapered radial vane (TRV), Alternate long and short vane (ALSV), variable diameter circular pillars (VDCP) were considered for the analysis. A rotor segment of 20° was considered for the numerical analysis due to its rotational symmetry. CFD results were in good agreement with the experimental analysis. The maximum deviation of the numerical results were about 12% from the experimental results. It is found from the analysis that among the different types of rotor configurations; variable diameter circular pillars (VDCP) rotor gives better rate of heat dissipation with more uniform temperature distribution in the flow passages. Hence for modern high speed vehicles VDCP rotor may be more appropriate.
