A VIRTUAL LABORATORY IN THE LABVIEW ENVIRONMENT FOR DETERMINING THE OPTIMAL PARAMETERS OF A FLAT-TOPPED REGULAR MICRORELIEF

Abstract

The aim of the work is to reduce the labor intensity and material costs in the process of experimental determination of the optimal parameters for the formation of a flat-topped regular microrelief (RMR) on the working surface of machine parts by replacing real experimental studies with virtual ones. To achieve this goal, a virtual laboratory has been developed in the LabVIEW environment to create virtual samples of machine parts with a flat-topped RMR with parameters close to the parameters of a real sample with a flat-topped PMR and determination of their optimal parameters.

The virtual laboratory in the LabVIEW environment allows to build Abbott curves based on the created surface profiles of virtual samples of machine parts with a flat-topped RMR and make a conclusion on the wear resistance of a part with such a profile. In comparison with the well-known virtual laboratory developed in the Microsoft Office Excel environment, the proposed laboratory in the LabVIEW environment has obvious advantages, among which are the following: it is much more user-friendly and has a user-friendly interface and wider ranges of input parameters, differs by one order of magnitude less in volume compared to the known one (300 KB vs. 6 MB). At the same time, the number of input parameters in the proposed virtual laboratory is one parameter less, which reduces the number of virtual studies by 2 times.

The developed virtual laboratory in the LabView environment for determining the optimal parameters of a flat-topped regular surface relief of machine parts can find wide practical application for creating virtual samples with a flat-topped RMP, as well as for conducting virtual experimental studies and determining the optimal parameters for forming the surface of a part with such a relief from the condition of providing it with highest wear resistance.
