Research On Pulsing Effect Of Automobile Mechanical Anti-Brake System

Research on hydraulic braking system (HBS) is a leading edge of modern automobile technology. The branch, which researches on automobile anti梑rake system (ABS), is very important. Because of the application of electronic control system, such as ABS, VDC and EIIB etc, a 搘ave effect?is established in braking pipeline. The thesis is based on the hydraulic braking simulation system (HBSS) of the type ofTJ7IOO Xiali automobile which is designed by the author accompanied with others. It does a deep research on transient braking pressure. A mathematical model is also setup. The HBSS is a PC-Based real time data sampling and controlling system. which is integrated with mechanical hydraulic pneumatic and vacuum system. It offers an all-new efficient and flexible means for the theoretical investigation, element development and product testing of automobile HBSS. The author did an overall experiment under both with and without ABS conditions. Based on the great deal of test data, system reference models of the two conditions were identified. With the identified transfer function, the author analyzed the 搘ave effect?by the means of simulation. The thesis discussed the influence of RCS MABS and foreseeable braking effect based on the practical data. The accomplished of the experiment changes MABS research work from computer simulation to physical model test under multi-condition. The result are valuable for setting up of correlative regulations, automobile parts electrotype, and ordination of MABS market. The author himself designed and made the vibration pump system which could provide steady wave source. The system make the real running test possible. At the same time, it provide the condition of designing and making sample ABS controlled by electronics. The simulation of the research means not only analyzing characteristic, but also providing a important theoretical and practical basis for the construction of braking regulation. It will also impulse the development of braking system design, element test and automobile initiative safe technology.
