Abstract
A calculation model which enables us to evaluate both performance as a system and behavior of each component (contact and stress condition, misalignment etc.) is required, especially, in case of mechanical system with a large number of components like Honda's new 10-speed automatic transmission (AT). So, we developed a full-assembly behavior analysis model of 10-speed AT based on dynamic explicit finite element method with applying simulation technology of component which was built before. In order to verify accuracy of the simulation model, static and dynamic torsion tests were carried out, and we compared the simulation results to the test results. In comparison, the simulation results were correlated highly with the static and dynamic test results. As the result, we confirmed that this analysis model has sufficient calculation accuracy. We also obtained a prospect of applying this technology to design considerations and problem solving in development.
