采煤机搬运车履带行走减速器动力学仿真

In this academic thesis, three-dimensional model for the epicyclic gear reducer of a certain coal cutting transport-truck is established by use of UG NX5.0 which is the software for CAD, and it is imported to ADAMS with simulation software through the interface bewteen UG and ADAMS. Then constraints and load are applied to this solid assembled model, and force of contact is specified with the meshing areas of gears, thereupon virtual prototype of epicyclic gear reducer. Finally dynamics simulation is carried out and some curves of contact forces are got from the result. The conclusions spply the Theoretical foundation and boundary conditions for continual finite element analysis, and have certain reference significancency to dynamics simulation study of epicyclic gear reducer in the other large-scale machine.
