The choice of the main parameters of vehicles of classes A, B and C

The object of the study are the vehicles of classes A, B and C on the European classification made in 2010 - 2015 in more than 80 enterprises in all automotive countries. The purpose of the study is to establish the dependencies curb and total mass of automobiles the main classification parameter is the overall length. The novelty of this work is that we studied a model of modern automobiles , while similar investigations were made on vehicles produced in the beginning of XXI century, most of which are now discontinued. Completed work is relevant because its results scientifically allow to choose when designing critical design parameters of passenger automobiles the curb and total mass. On the basis of statistical processing source data were obtained analytical and graphic dependences of curb and total mass of automobiles from their overall lengths in each class and, in addition, in the largest class C. These dependencies are set separately for sedan, hatchback, coupe and cabriolet automobiles. In total, were analyzed 289 automobile models. A large volume of the investigated models allowed to obtain statistically reliable results. The article shows that the accuracy from 7.5% to 14.4% of the dependency between mass and overall length of vehicles of all studied classes can be approximated by polynomials of second order. The results of the study are recommended for use in design and research organizations of automotive companies for a reasonable choice of design parameters of the designed passenger cars.
