Functionality of the modernized onboard system for monitoring of functional state of vehicle operators which based on the system of maintenance of working capacity of drivers are considered. Automatic interpretation of functional state of operators are carrying on the results of the analysis of the dynamics of electrodermal changes parameters and "intensity" of performance of some "typical" and/or "basic" algorithms of activity or their fragments. The onboard system of monitoring, first of all, is intended for development existing and elaboration of new methods for increase of efficiency of drivers functioning, as well as carrying out of experimental researches, is performed during the vehicle operator algorithms of activity. Received results can be used for a substantiation of a rational mode of work and rest, an evaluation of interrelation between actions of drivers and criteria, their characterizing.

SCHEMATIZATION AND CALCULATION OF MOBILE MACHINE PRESENTED AS MULTIBODY SYSTEM. REGULAR MECHANICAL SYSTEMS

The role and place of schematization is considered in calculating the mobile machine which is regarded as a multibody system. Unlike widespread approaches "Object - Equations - Solution", it is proved necessity of the initial stage for correct schematization of the object and the approach "Object - Mechanical system - Calculated model - (Symbolical model) - Equations - Solution". The concept of regular mechanical system, rules for construction of correct mechanical models consisting of elementary mechanical objects is offered and proved.
