Due to the complexity of gear tooth profile and the time-varying feature of gear contact ratio

it is difficult to use existing theoretical methods to study its dynamical behavior.Therefore

it is significant to seek for an easy and reliable new way to study its dynamical behavior.By taking apair of non-circular gear transmission of a specific transmission ratio function and a pair of cylindrical gear transmission as a contrast experiment

based on ADAMS

the experimental results with the corresponding theoretically calculated values from the angular velocity

angular acceleration

meshing force as well as other dynamical behaviors are compared.This study provides a new idea not only for the intensive research on the difference between non-circular gear transmission and cylindrical transmission

but also for the application of the modifying achievements of cylindrical gear to the field of non-circular gear transmission.
