  • Drift trash barrier was a kind of multibody system made up of float boxes and hinges. The float boxes were simplified to rigid bars, and the governing equations for them were established based on the multi-body dynamics theory. An iteration strategy was also proposed to obtain a numerical solution. To validate the proposed model and solution, a scaled model test was designed and the test results illustrated the validation of the model and the solution. Numerical example compared the results given by the proposed model and classical model. In addition, a judge method of the self-locking state of the drift trash barrier and the change process of tensile force were presented when the water level fell.
