Application of Virtual Instrument Technology in Automobile Engineering

Virtual instrument technology is important developing way of the morden automated test technology and its system.The developing trends of virtual instrument are approached.According to the characteristics and key technology of virtual instrument, application of the technology in automobile engineering is stressed.In this paper, two kinds of virtual instrument for automobile are intruduced.They are the automation instrument for hydrodynamic torque converter and the measurement system for automobile comprehensive performance.The former is used to test the performance parameters of the hydrodynamic torque converter which runs in different speed and port pressure.With user interface, experiment design, configuration of system resource, replay and print of data are performed.The later is used to calculate and analyze automatically the parameters of brake and performance, and can print relevant curves.So virtual instrument can replace some current test instruments and has broad applicating prospects.
