In this paper,the dynamic balance detection system of the automobile wheel hub is developed by using the forcesensor and the automatic filtering,thus the on-line detection of the residual unbalance of the automobile wheel hub in the pro-duction line is realized. Focus on design of the detection system for unbalanced quantity,the digital signal processing technol-ogy is combined with the dynamic balance technology by use of the Visual Basic software virtual instrument technology so as torealize the data acquisition,analysis and process,and results display of the hub vibration signals,and thus the dynamic bal-ancing system of the automobile wheel hub is come into being. The experimental results show that the test method can realizethe dynamic balance detection and location marking of automobile wheel hub in automatic line,thus it has certain applicationvalue.
