Research of technical and economic indicators of loaders

Abstract

The article deals with the results of the analysis of indicators of telescopic loaders with a carrying capacity of 2000 - 4000 kg. These indicators are most often used to perform loading and unloading operations in agricultural enterprises. The base of characteristics of various models of telescopic loaders was formed. The following characteristics: load capacity, weight, boom lift height, power were selected by the authors for analysis. The selected parameters were grouped into specific groups so that the parameters of each of the groups mainly reflect changes in any one of the significant characteristics of the original functions. The connection with the use of correlation analysis has been established between the three parameters selected for research, namely: load capacity and weight; weight and height of lifting; weight and power. The parameters of the functional characteristics of energy intensity and energy saturation have been calculated additionally. Regression analysis was used to assess the influence of some factors on the selected parameters of the functional characteristics of telescopic loaders (energy intensity and energy saturation). This analysis made it possible to obtain a multifactor mathematical model. Regression equations have been obtained that reveal the relationship between energy saturation and energy intensity and power parameters and weight of the loader. It is established that the greatest influence on energy saturation has the engine power, on the indicator of energy saturation – the weight of the loader, respectively.

Correlation-regression analysis can be based on the process of improving the efficiency of telescopic loaders for agricultural work. The influence of the main parameters of the loader on the functional features of structures: energy saturation, energy intensity, specific power, etc. is analyzed in the article.
