运用理论和实测的方法，分析了汽车连杆的动态特性，采用有限元法对所分析的实体进行建模，然后进行了模态分析。在实测中，运用LabVIEW对汽车连杆进行了实测，采用正弦扫频的方法，得出了连杆的固有频率。对比理论结果与实测结果，二者结果相符合，证明该方法是正确的，该测试系统提供了一种新的连杆固有频率测试方法，具有一定的参考价值。

In this paper , theoretical and experimental methods were used to analyze the dynamic charac-teristics of the connecting rod .First, the finite element method was used to build the physical modeling of the connecting rod , and then the modal analysis was carried out .In the measurement , LabVIEW was used to meas-ure the automobile connecting rod's dynamic characteristic , that is to say , sine sweep method was used to get the results of the natural frequency of the connecting rod .Comparing the theoretical results with experimental re-sults, the two results proved that the method is correct .The test system provides a new testing method and has a certain reference value .
