Space Equilibrium Configuration and Tensile Forces of Drift Trash Barrier Based on Multi-Body Dynamic

Department of Engineering Mechanics, Wuhan University, Wuhan 430072, P.R.China

摘要

摘要: 漂浮式拦污排为多个浮箱通过铰接组成的多体系统．将浮箱模型简化为刚性杆件，基于多体动力学理论，建立了漂浮式拦污排的运动控制方程，并给出了相应的数值求解方案．模型试验表明了数值模型及求解方案的有效性．数值算例结果表明，传统的悬链线假设得到的结果误差较大．此外还讨论了平衡状态下拦污排发生“自锁”状态的判断方法及水面下降时的张力演化过程．

Abstract: 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.
