DIGITAL MODELLING AS A TOOL FOR REFINING THE DESIGN PARAMETERS OF A METALWORKING WORKSHOP VENTILATION SYSTEM

Abstract

The paper considers the possibilities of combining calculation and analytical methods and approaches of modern digital 3D modelling, using the example of the SolidWorks software package, for the operational optimisation of design solutions for setting the parameters of ventilation systems in production facilities. On the example of a metalworking workshop, where it is planned to change the configuration of equipment for repair work and equipment modernisation, the possibility of optimising the workspace in terms of ensuring the air quality of the working area is considered. Lathes, drilling and grinding machines are considered as emission sources. The parameters of the ventilation system were calculated: the total heat emissions from the equipment were determined, and the required air flow rate for heat assimilation and for the removal of harmful emissions such as dust and aerosol was calculated. Based on the maximum air exchange demand, the diameters of air ducts for different sections of the network (from 355 mm to 700 mm) and the total pressure loss (670.9 Pa) were calculated, which made it possible to justify the parameters of forced ventilation of the working area. Based on the creation of a three-dimensional model of the workshop and its ventilation system in the SolidWorks software package, the distribution of air flows was modelled using CFD analysis, which made it possible to visualise air movement, identify areas of uneven distribution, and verify the rationality of the design solution. Comparison of the results of analytical calculations and digital modelling showed good convergence.
