摘　　要：针对海洋设施表面的硬质海洋污损物设计了一种接触式仿生除污结构,通过理论模型及实际试验对不同结构的除污性能进行了测试,并根据试验结果对其除污机理做出了分析。结果表明:最大直径(D_m)和纵向缩减率(Y^(*))相同时,直径缩减率(D^(*))在6%~8%的结构具有更好的除污性能,而在D_(m)和D^(*)相同时,随着Y^(*)增大,除污性能随之提高。分析其原因,D~*和Y^(*)是影响除污过程中切向刮擦力的主要仿生结构参数,对D^(*)和Y^(*)进行适当设计,可以提升仿生除污结构的除污性能。结合仿真模拟和实际试验可知,D^(*)=8%的结构具有最佳除污性能。A contact bionic decontamination structure was designed for the hard marine pollutants on the surface of marine facilities.The decontamination performance of different structures was tested by theoretical model and practical experiment,and the decontamination mechanism was analyzed according to the test results.The results show that when the maximum diameter (D_(m)) and the longitudinal reduction ratio (Y^(*)) are the same,the diameter reduction ratio (D^(*)) is between 6%~8%,the structure has better decontamination performance,and when D_(m) and D^(*)are the same,the decontamination performance increases with the increase of Y^(*).Analysis of the reasons shows that D^(*) and Y^(*) are the main bionic structural parameters that affect tangential scraping force in the process of decontaminating.Proper design of D^(*) and Y^(*) can improve the decontaminating performance of the bionic decontaminating structure.Combined with simulation and actual test,it can be seen that the structure with D^(*)=8% has the best decontamination performance.
