Based on the urgent need that pier protective device primarily designed needed to be tested its crashworthiness by the impact of ship in multi - situation, etc in multi - angle and multi - water, the writer analyzed the critical elements that affect the simulation of the collision between ship and pier protective device, and found the feasible way to deal with the conflict between calculation efficiency and precision. using this method and employing ansys / ls - dyna program, which is the universal nonlinear dynamic analysis software, a head - on collision between ship and pier protective device designed for guanzhou river bridge is simulated and presented, the simulation of time history course of full - scale mini - collision between ship and pier protective device was taken into reality with a spot of elements ( less than 21000 ) and scanty time ( 9 hours on p4 pc )
本文在前人研究的基礎之上，結合船橋碰撞實例，對碰撞計算機模擬模擬的關鍵技術進行了研究，在效率與精度的矛盾中找到平衡，對一艘2000噸級散貨船橫橋向正撞廣東管洲河大橋橋墩防撞鋼套箱這一種工況進行了計算機模擬模擬，實現了以較小的單元和較短的時間模擬碰撞的時間歷程，模擬滿足工程精度要求，解決了目前碰撞模擬計算周期太長的問題，同時模擬模擬得到的結論對該類防撞裝置提供了有價值的參考。
