Research On Test Platform Of Engine And Automatic Transmission And ABS Test

Along with electronic technology and computer technology applicating on the automobile, Cause the automobile structure, the performance have to change very much, also proposed the new demand to the automotive engineering teaching and the experimental facility. However, for adapts the automobile industry high speed development for the improvement, raises the teaching overall level, strengthens the student to practice ability raise, the development comprehensive practice teaching is extremely essential.This article embarks from the automobile combined teaching experiment, the use virtual instrument technology development the engine, the automatic transmission, ABS comprehensive testing experimental Platform to adapts the automobile industry rapid development.First, based on the engine bench test, the automatic transmission bench test and the ABS system, take the three union identical test platform in, According to the automobile fundamental construction, through the charging turbulent flow load and the measurement system, the road simulation system, Joint the engine, the automatic transmission and the ABS braking system. Constitute the structure of the combined teaching experimental Platform.Next, according to the virtual instrument hardware composition and the characteristic, uses the open style, determined the observation and testing system uses the hardware module, and has carried on the data gathering system and the resistance disturbance system designing.Third, according to the testing request, chooses LabVIEW as the software platform, and design the examination procedure. In the main Panel has used the While structure, the Sequence structure and the Case sub-program. The main function is carries on the various single items test project the choosing, the experimental prompting, the channel and the sampling frequency selection and the stop movement and so on. The application procedure is divided into five sub-program and a virtual oscilloscope, including engine fuel oil economical test system, engine power test system, automatic transmission correlation test system and ABS brake test system. Through the testing system application experiment, the confirmation use virtual instrument technology carries on the automobile combined teaching experiment to observe and control the system the development is feasible.
