| Abstract: | A computer-aided measurement device for dynamic parameters of second-order system is designed based on virtual instruments.It includes the bracket design of the device,the chose of USB2008 data acquisition and FXB-V serial sensor.The free vibration waveform of the spring-mass system can be collected,displayed and saved by the computer.In addition,the dynamic characteristics (natural frequency and damping ratio) of the second-order system can be calculated automatically. |
