This paper introduces a method to deal with dynamic force measurement and its realization ,which is designed for experimental teaching in load contrast tests .Dynamic force signal which is obtained by sensor is amplified and A/D converted by measuring circuit ,and is sent to PC through USB bus .The force waveform can be displayed and stored by the LabVIEW-based software system . Measuring results show that experimental data recording and precision problems were solved .This system also provides a platform for experimental result analysis and teaching style development .
