So research and development on it were taken in the world , which have an important influence on environment protection , energy saving and technology advancement aimming at the peculiarity and trend of hydraulic hammer , experiment equipment of the new type of it has developed . on the guidance of dynamics theory , by means of technology of dynamical measurement and signal processing and on the basis of experiment data and simulation result , the changing rule of major functional parameter of hydraulic hammer was researched profoundly and systematically . thus dynamical model and computing method whose hydraulic system was applicable to hydraulic hammer of middle and small type was presented 本论文针对液压打桩锤的特点和发展趋势,研制了新型液压打桩锤的实验装置,并以动力学基本理论为指导思想,以动态测试和信号处理技术为手段,以实验数据和仿真结果为依据,对液压打桩锤主要性能参数的变化规律,进行了深入和系统地研究,进而提出了适合小型液压打桩锤的液压系统动力学模型和计算方法,为产品开发提供了科学依据。
This paper is original from an item on technical innovation in line electric pump limited corporation , which is supported by anhui economic and trade committee . the project mainly researches on the measurment theory of the functional parameters about pump , as well as the error analysis and how to deal with the data measured by device . the system affimly reaches the precision in b level provided by state 本论文所研究的课题来自于安徽莱恩电泵公司经安徽经贸委立项的一个技改项目,主要进行水泵性能参数测试的理论研究、误差分析和测量数据的处理,并确保测试系统达到国家规定的b级精度要求。
Based on an experiment performed on the piston ring - cylinder bore wear tester , liquid - solid lubrication is investigated in this thesis . the wear of the samples under different lubrication conditions ( the solid concentrations are 0 % , 0 . 02 % and 0 . 1 % by weight ) are discussed . the variations of the surface topography , especially the statistical parameters and functional parameters are studied , and the reasons that cause the variations are analysed 本研究基于活塞环-缸套摩擦磨损台架实验研究了液-固二相流体润滑的问题,探讨了润滑油中不含固体颗粒、含有0 . 02和0 . 1纳米颗粒三种润滑状态下的磨损情况,并进一步研究了液-固二相流体润滑状态下试件表面形貌特性的变化,主要是统计参数和功能参数的变化,并探讨了引起变化的原因,为更深入的液-固二相流体润滑问题的研究以及表面形貌设计提供理论上的参考。
