Tooth contact analysis is an integral part of the gear design process. With the help of these simulation tools, it is possible to calculate the excitation caused by a tooth contact (Ref. 1). Usually, the load-free transmission error or the total transmission error under load is used for this purpose. However, the calculation with the tooth contact analysis ZAKO3D allows only a quasi-static consideration of the excitation. To better evaluate the behavior in the overall system, it is therefore necessary to perform a dynamics simulation. However, the main disadvantage of such dynamics simulations is the much longer computing time compared to quasi-static tooth contact analyses due to the high computational effort.

Closed-loop control systems can handle a wide range of motions with a wide range of loads if the control system and the mechanics of the system are properly designed for the task. A couple of the more difficult combinations to design for are high inertial mismatches and backlash with hard gearing. The question is not just how to make the system stable but also how to get the desired performance.
