Statistical tolerance analysis of bevel gear by Tooth Contact Analysis and Monte Carlo simulation
Résumé
Tolerancing decisions can profoundly impact the quality and cost of gears. To evaluate the impact of tolerance on gear quality, designers need to simulate the influences of tolerance with respect to the functional requirements. To do so, they use AGMA or ISO tables, or they perform experimentations. The first approach is not very flexible on the other hand the second approach is expensive. We have proposed an approach to analyze the tolerances. This approach includes a vectorial dimensioning & tolerancing model which allows gear conventional tolerancing practice and geometric tolerancing practice, a digital simulation based on Tooth Contact Analysis and Monte Carlo Simulation.
