基于虚拟仪器的减震器橡胶衬套试验系统

Test System of Damper Rubber Bush Based on Virtual Instrument

基于减震器橡胶衬套实车使用工况,利用数据采集硬件设备和LabVIEW软件,开发出基于虚拟仪器的橡胶衬套试验系统。该系统由变频电机驱动曲柄连杆滑块机构获得简谐激励,滑块通过双弹簧加载机构将简谐激励柔性施加到橡胶衬套上。橡胶衬套实例试验表明,试验系统性能稳定、使用方便、人机操作友好,能满足橡胶衬套动态性能测试和疲劳试验要求。

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 harmonic excitation was acquired through crank slider mechanism driven by frequency conversion motor of system and applied to the rubber bush by slider through double spring mechanism.The system was stable,offering simple operation and friendly man-machine interface.It met the requirements of dynamic performance test and fatigue test of rubber bushing.
