Bubikon, Switzerland. The first part of the training course uses the calculation of the face load factor as an introduction to the more detailed theory of contact pattern calculation. The course explains essential issues such as modeling and stiffness, and also goes into detail about how to check and interpret the results. The second part of the course covers the special topics involved in contact analysis, such as how to take into account shaft deformation and planetary gear units. Participants will then reinforce what they have learned by using the powerful sizing and optimization functions. The second part of the workshop offers the possibility to deepen and practice the optimization strategies learned in the Contact pattern training. The trainer will support and advice the participants individually. This workshop is restricted to a maximum of 10 participants.
