摘要根據艦船原型結構板架模型，提出了新型抗冰結構板架模型，采用凍結冰模擬冰體，對兩種板架結構在相同冰體撞擊下的結構動響應開展模型試驗，并建立相應的光滑粒子流體動力學-有限元法(SPH-FEM)數值模型．通過對試驗結果和數值仿真結果的對比分析，驗證了提出的新型抗冰結構型式的抗冰效果，相同工況下結構最大變形數值計算結果與模型試驗結果的最大偏差為8.65%，冰體最大撞擊力數值計算結果與模型試驗結果的最大偏差為5.11%，表明SPH-FEM數值仿真方法具有良好的工程適用性．

Abstract According to the ship’s prototype structural slab model，a new ice-resistant structural slab model was proposed．The frozen ice was used to simulate the ice body．The model test was carried out on the dynamic response of two slab structures under the impact of the same ice body，and the corresponding smooth particle hydrodynamics-finite element method (SPH-FEM) numerical model was established．Through the comparative analysis of test results and numerical results，the anti-ice effect of the newly proposed type of ice-resistant structure was verified，under the same working conditions，the maximum deviation between the numerical calculation result of the maximum deformation of the structure and the model test result is 8.65%，and the maximum deviation between the numerical calculation result of the maximum ice impact force and the model test result is 5.11%，indicating that the engineering applicability of SPH-FEM numerical simulation method was verified．
