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.
