Taking the gear transmission system as study object

based on the mechanical dynamic simulation technology

the dynamic characteristics of gear transmission systems is studied.Dynamics simulation model of multistage gear transmission system of gearbox is established

which is based on the software of Pro/E and ADAMS.The restraint

loading

the adding method of driving force and contact force

some parameters values are given as condition

the engaging force and frequency of gear transmission at all levels are obtained.The simulation results show that the error between the simulation value and the theoretical value is quite small.It indicates that the simulation method and parameter values are reasonable

correct and credible.It can provide as reference for the multistage gear box design and calculation.
