Application of Nonlinear Dynamic Analysis in Calculation of Characteristics of Frictional Draft Gears

摘要

The computing finite element model of the elastic-frictional draft gear was developed with application of the Siemens NX software package. The theoretical foundations of computational methods laid in the NX Nastran software system were analyzed. The optimal solver settings that make it possible to achieve the convergence of the solution without sacrificing acceptable accuracy were determined.
