Abstract

The problem of increasing the accuracy of determining the mass and center of gravity of vehicles in order to reduce accidents and improve safety during transportation is considered. A comparative analysis of various systems and methods for determining the mass and center of gravity of vehicles is carried out. It is shown that it is preferable to use non-contact methods and instruments for measuring mass. The technique of contactless determination of the vehicle mass by the vertical movement of its body is presented. A simulation model of the system for contactless determination and remote control of the mass and center of gravity of vehicles has been developed. On the example of aircraft, the possibilities of modeling this system using various interpolation methods are considered. For Airbus aircrafts in the MathCad program experiments were carried out using linear interpolation, fitting methods, least squares and Lagrange polynomials. The principles of constructing a system for contactless determination of the mass and center of gravity of vehicles are proposed. The choice of methods and means of measuring the airplanes fuselage vertical displacement for the implementation of such a system has been substantiated. The research results provide the possibility and perspective of building a system for non-contact remote control of the mass and center of gravity of airplanes, as well as other types of aircraft.
