Development of Test Bench for Measuring Performance of Magneto-Rheological Fluid Brake

Theoretically， the quality of a vehicle braking system is mainly determined by the performance of brake. In order to coordinate the development of new magneto-rheological(MR) brake， a specific test system is developed and discussed in detail. The test apparatus system consists of measuring module and load applied module. For the system， it is a crucial problem to realize real-time measurement and display of data. Based on the LabVIEW software， the measuring module， including the speed torque sensor and the data acquisition card (DAQ card)， is ultimately developed. The test system is validated to be reasonable and practical by the successful application of braking performance tests of MRB.
