摘　　要：结合虚拟仪器的构成特点与优势,利用DASYLab软件设计了动态应变信号采集分析系统,用于采集组合梁模型在运动小车作用下的应变值,并对采集信号进行拟合与输出显示。在桥梁工程检测中应用该系统进行动态应变测试,取得了比较满意的效果。Combining the constructions and the advantages of virtual instrument, the software of DASYLab is used to design a collecting and analyzing system of dynamic strain signal, which is applied to collect the strain of a combine beam model under the load of a moving trolley, to fit and output the collected signals too. In the test of bridge engineering, good results are achieved by using this system to test the dynamic strain.
