The parameteric quick modeling on gear is realized after it is developed the UG menu of parametric modeling by the aid of redevelopment tool

UG/OPEN API.After importing the assembly of the gear transmission model into ADAMS

the dynamics simulation is carried out

and the correctness

validity of a virtual prototype model is validated through the analysis data of the simulation and the theoretical calculation.Application of contact force data by aid of ADAMS simulation

the design simulation is achieved in the UG.Through the analysis data of the simulation in UG

the low vibration property and the low noise and the reliability of gear strength is verified.
