| Abstract: |
| According to the actual working conditions of damper rubber bush，the rubber bush test system based on virtual instrument was developed by using data acquisition hardware devices and LabVIEW software.The crank connecting rod-slider mechanism was drived by frequency conversion motor of system，harmonic excitation was acquired and applied to the rubber bush by slider through double spring loaded mechanism．Instance test results of rubber bush showed that，the system characterized stable performance，simple operation and friendly man-machine interaction，and could meet requirements of dynamic performance test and fatigue test of rubber bushing. |
