Abstract: In order to meet the requirements of research on rotary magnetorheological fluids (MRF) dampers, a system for damper performance test was developed based on the universal hardware platform of industrial computer and the LabVIEW software development tools. The system integrated the application of computer, virtue instrument, signal measurement and process, and automatic control technologies to realize the automatic control of damper performance test process. It has the functions of motor speed control, exciting current scan, test signals (such as speed, torque, temperature signals from sensors) collect, display, store, and analysis. It is easy to be extended and maintained, and has friendly human-machine interfaces. The actual applicatiion indicates that, the test process can be automatically carried out, the test time can be effectively saved, and the test accuracy and efficiency can be apparently improved.
