Research on Mechanical Behavior and Dynamical System Simulation of Crashworthy Arresting System in Waterborne Safety

In waterborne safety management of sluice on Suzhou River estuary in Shanghai, the Crashworthy systems are used for ensuring the safety of sluice gate and the arresting net is the core system. It is the first time that the arresting net is used in engineering of waterborne safety. Dynamical system simulation and mechanical analysis of crashworthy arresting system are studied for waterborne safety of sluice on Suzhou River estuary in Shanghai. The axial stress distribution cures of main cables and nylons are drawn, and the boat´s acceleration and reaction force are gained. According to the results of numerical simulation, mechanical properties in operating process are investigated, and the working principle of arresting system is introduced. A finite element model to simulate the arresting system is presented, and the results are contrasted by mechanics analysis. Through analyzing the results of simulation, the arresting system can effectively keep the going wrong boats off. The proposed method is shown to provide a reference to design of arresting system.
