Research of Methods of Discrete Integration of Dynamics of Mechanical Engineering Designs

Abstract

Innovative methods and algorithms of numerical calculations of big systems of the differential equations, to which problems of dynamics of multibody element mechanical engineering designs are given, are rather simple in use, standardized by types and classes of mathematical models, presented by the closed modules in different packages of application programs. Similar ready means save time of modeling and calculation. At the same time the reliability of the received results turns out to be approximate confirmed by the authors’ calculation model for calculating the dynamics of the crank gear mechanism with elastic-damping coupling by classical methods and the NSTIFF method of MATLAB package.
