摘　　要：以多功能融合电机泵马达配流副为研究对象,利用仿生非光滑表面效应设计出几种不同凹坑排布的配流盘,并通过不同工况下光滑表面和非光滑表面配流盘的对比试验,探讨非光滑表面对配流副润滑性能和减摩性能的影响。试验结果发现:非光滑表面比光滑表面有着更好的减磨减阻特性,其中最大减阻可达46.3%,减磨总体超过53%;非光滑表面中的凹坑可以储存试验中产生的磨屑和杂质,还可以储存海水,在润滑条件不良时凹坑内部海水可被带入到摩擦面从而改善润滑状态;试验后配流副试样接触角会降低,表面能会提升,这说明摩擦磨损试验使得配流副试样更加亲水,这有助于海水润滑膜的形成,从而降低摩擦面的摩擦磨损。Taking the multifunctional integrated motor pump as the research object,several port plates with different pit arrangements were designed based on the bionic non-smooth surface effect.Through comparative experiments of smooth and non smooth surface port plates under different working conditions,the influence of non smooth surfaces on the lubrication performance and friction reduction performance of port plates was explored.The results show that the non-smooth surfaces have better anti-wear and friction reduction properties than the smooth surfaces,with the maximum friction reduction of 46.3%,an overall wear reduction of over 53%.The pits on the non-smooth surfaces can store the wear debris and impurities generated during the experiment,as well as seawater.When the lubrication conditions are poor,the seawater in the pits can be brought into the friction surfaces to improve the lubrication conditions.After the experiments,the contact angle of the port plate samples will decrease,and the surface energy will increase,indicating that the friction and wear test makes the port plate samples more hydrophilic,which helps to form a seawater lubrication film and reduce the friction and wear of the friction surface.
