Hs-b Sliding Bearing Test Bed Computer Testing System Design And Research

For a long period of time, sliding bearing work beach rests on the stage of hand operation, experimental efficiency, effect is at question. Scientific researches on HS-B sliding bearing work beach are made, corresponding software and hardware are designed in this paper.In the system design, the communications between epigynous PC and hypogynous SCM follows the RS-232 criterion, AT89C51 chosen as core hardware, voltage conversion circuit, display circuit, data collection circuit are introduced. In soft section, VB6.0 chosen as develop tool, modularization design method are adopted, serial port communications module, sliding bearing film force test module, print preview module, friction characteristic experimentation module are designed and introduced.On the basis of liquid lubricant theory, through the investigation of sliding bearing film force law, a simulation method of sliding bearing film force radial distribution is introduced. Experiment indicates simulation curve and actual curve are consistent in shape, and precision reach the demand of the factory. This shows feasibility of the method.The disposal methods of experimental data are also discussed. Through adoption of curve-fit and average filtering methods, the system's dependability, veracity are achieved.HS-B sliding bearing work beach computer measure system armed with technique of data processing, serial port communications becomes a late-model high-school experimental teaching system though the research.
