THEORETICAL FOUNDATIONS OF THE DEVELOPMENT OF A BULLDOZER DESIGN THROUGH THE USE OF MULTIVARIATE PARAMETRIC ANALYSIS

The article presents the scope, purpose and design of bulldozer. main brands bulldozers used in our republic are given. Their characteristics considered, such as: weight, power, blade width height. As a result analysis parametric information, standard deviation, average value, coefficient variation, asymmetry kurtosis were determined. A correlation matrix has been compiled that describes relationship between parameters machines. Based on results obtained, cluster was carried out StatGraphics Centurion software. histogram distribution bulldozer indicators is constructed, with determination left right boundaries, number models interval. Using obtained data, equations for determining technical level formed. equation, prospective values machine
