Comprehensive consideration the influence of various kinds of random error on the dynamic characteristic of gear drive system

the reliability evaluation is difficulty in gear drive design field. The effective evaluation of gear drive system is a key job for realizing the system dynamic optimum design.Firstly

combining the advantages of the Pro/E and ADAMS programming techniques

aparametric virtual test model for the gear drive system is built and the dynamic characteristic curve and data of each part are obtained.Secondly

by using Monte Carlo method

apseudo-random number generating sub-routine is written to simulate the distribution of the drive system different random errors.Considering the composite effects of the errors

a simulation is implemented and mass system dynamic characteristic data are obtained.Lastly

statistics these data in VC++software

the gear drive system reliability is calculated and the reliability evaluation of the dynamic characteristic under the influence of random error of gear drive system is carried out.This method is simplicity

convenience and high accuracy and with no need for building and solving complicated mathematical model.
