Kinematic Design and Simulation of the Transmission Then the simulation is carried on to validate the kinematic design result. All the gears and shafts are first modeled and assembled in certain solid modeling software, such as Solidworks and Unigraphics, and then imported into the kinematic and dynamic analysis software ADAMS/View to do the kinematic simulations.
