Abstract:

Purpose. To prove the reasonability of computer simulation as an instrument for study of mechanical system dynamics, which allows us to substantiate the appropriateness of newly-developed technical solutions.

Methodology. We have compiled the system of differential Lagrange equations of the 2nd order and them by means of Wolfram Mathematica software. The initial conditions and mass-inertia data have been prepared by means of CAD Kompass 3D. The results of simulation have been verified by CAM “Universal Mechanism”.

Findings. We have proposed to analyze dynamics of mechanical systems of mining rail transport by the method of CAD simulation. It allows us to use CAD model parameterization to vary model characteristics on the stage of development with dynamics indices assessment, mechanical stress of elements, reliability and lifetime estimation subject to exploitation conditions. The solution of those tasks is realized in corresponding mathematical models, which describe technical solutions or in the 3D models developed in CAD/CAM software. This allows describing inertial, geometrical and kinematical parameters, force interaction.

Originality. Verification of theoretical and experimental research becomes possible due to modern approaches of dynamic systems simulation. Preparation and implementation of the initial data created in different CAD/CAM software in one mathematical model provides the possibility to carry out plenty of research with different system parameters.

Practical value. We receivedthe possibility of the obtained data exchange between separate parts of a mathematical model. This brings the time saving and increases the level of scientific study.
