RecurDyn/Gear provides the easier modeling and the analysis of complicated gear train system in the graphical user interface. RecurDyn/Gear can analyze vibration characteristics and DTE (Dynamic Transmission Error) which is occurred from the real contact characteristic among gear teeth, considering user-defined backlash and tolerance. Also, the post-process function provides to check the information about the contact normal forces and friction forces in the contact point at each time step.
