Further, the actual temperature of a brake disc is calculated according to the vehicle braking speed (v), the braking time (t) and the braking force (F), and is displayed on a display; and the temperature conditions of the brake disc are returned to train drivers in real time, so that the train drivers can select proper measures according to the temperature conditions of the brake disc.
Description
Technical field
the present invention relates to a kind of brake disc temperature-controlled process.
Background technology
when guideway vehicle normally runs, in braking procedure, electric braking and air brake are all worked.But there is the operation mode that electric braking lost efficacy sometimes.Because electric braking force reduces, in order to ensure braking deceleration, reaching the stopping distance of regulation, needing to increase air-making power, thus in braking procedure, producing higher heat.When the temperature of friction material exceedes the limit that can bear, its hydraulic performance decline, cannot ensure safe stopping distance, sometimes also there will be thermal crack equivalent damage.At present in engineering, usually adopt and calculation of Heat Load is carried out to pass judgment on thermal load performance to brake system.Calculation of Heat Load according to different operation modes, overall trip speed, load condition, brake equipment etc., calculate friction material and brake disc in circuit operation time temperature conditions.When under some operating mode, when the temperature of simulation is too high, in order to ensure the performance of friction material, reaching normal stopping distance, needing omnidistance or part speed limit.Speed limit then means the punctuality that have impact on vehicle operating.In train travelling process, because passenger flow volume is uncertain, there is larger difference with emulation in actual load condition, actual braking force, actual deceleration degree etc.The input parameter of calculation of Heat Load cannot be accomplished with real-world operation consistent, and the evaluation capacity of calculation of Heat Load is limited.Monitor the actual temperature of brake disc and friction material if think in real time, determining when to need fall-back to ensure train braking performance, needing reload temperature sensor on bogie truck by monitoring in real time, technical risk is comparatively large, and cost is higher.
