| Abstract: | In order to research the fatigue properties of the connecting rod with tension and compression loads,the test rig was studied based on LabVIEW development environment and CompactRIO embedded controller,and the hydraulic servo loading system was adopted.In engine actual conditions,the connecting rod mainly bears circular alternating tensile and compressed load,and the maximum compressed load is larger than the maximum tensile load,so the asymmetrical loading method and the PID control on the loads were adopted.At last,a certain type of connecting rod for example was taken,the loads calculation,the asymmetrical loading method and the PID control were simulated in the LabVIEW.The results show that the test rig of which the function can be realized has a good performance. |
