Abstract：Used a simply supported beam as the research object, proposed a dynamic load location identification method of "Law of the minimum coefficient of determination". Forecasted the virtual location of the load, two equivalent dynamic loads of virtual location were identified based on two groups of seclecting acceleration responses in the frequency domain. Ordered the difference of the two to be an optimal target variable, the virtual position that the target variable corresponding to is the real loading position. Simulation and experimental results show that the method is correct and feasible.
