LOUVERED PROTECTION AGAINST EXCESSIVE INSOLATION OF THE CABIN OF MOBILE ENERGY UNIT
In modern mobile energy units (MEU), various devices are used to create comfortable and safe working conditions for operators. However, the problem of localization and neutralization of incident and penetrating radiant streams into the cabin has not been completely solved as of yet. Famously, insolation negatively affects the human body, especially the organs of vision. The purpose of the study is to substantiate a technical solution for regulating and neutralizing excessive penetrating insolation when a mobile energy unit is performing various technological operations. The authors proposed the design of louvered plates and means of their technical implementation, providing full protection of glass from optical radiation of any direction in addition to the air conditioning system in the cabin of MEU; substantiated the logical scheme of the eye protection device from excessive optical radiation of the cab windscreen due to electronic control unit introduction into the design; obtained an analytical expression for calculating the minimum cutoff width of one plate relative to the other, protruding beyond the axis of the part of the louvered plate; carried out computational studies of the numerical value of the minimum cutoff width of the plates, depending on the possible step of their installation on the windscreen with special references to John Deere 6B tractor; revealed that with an increase in plates spacing, the minimum width of their overlap increased linearly. The proposed technique makes it possible to determine the minimum overlap width in the practical range of changes in the inclination of the windscreen, depending on the average angle of its inclination. This dependence is represented by a polynomial equation of the second degree.
