| Abstract: | 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. |
