  2. 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。
  3. Based on the solving technique of explicit non - linear finite element method and the mechanism in ship - anti - collision equipment collision, this paper develops numerical simulation to collision process of a ship and an anti - collision equipment, then studies the influence of uncertain factors in the collision problems and gives some suggestions to improve the anti - collision equipment

    摘要在研究船橋墩防護裝置碰撞機理的基礎上，結合實例探討了碰撞問題中的諸多因家（如碰撞位置、防護裝置的結構尺寸以及碰撞速度等的變化）對防護裝置抗撞性能的影響，並據此對橋墩防護裝置提出了改進意見：通過模擬計算，改進防護裝置的板厚以及板上筋的結構尺寸；在防護裝置的內圍壁與橋墩之間放置橡膠吸能元件或在防護裝置的外圍壁安裝橡膠護舷件，以加強防護裝置的吸能作用。
  4. Comment on protection device of bridge piers

    橋墩防撞裝置評述
  5. In the end, the damage process and energy absorbing are obtained, which are of great value for this kind of pier protective devices design

    本文共分六章，第一章為緒論，介紹了國內外船船碰撞、船橋碰撞和橋墩防撞裝置的研究概況。
