Predicting fatigue performance of fiber reinforced plastic gears
For gear applications it is key to accurately predict short- and long-term mechanical performance. Applications with different load cases result in a combination of failure modes. One tends to perform dedicated application tests in each design phase. However, with fundamental material knowledge and gear-application know-how one can combine test results obtained via simplified tests, such as standard tensile bar fatigue testing or simplified gear test results, into a model that provides accurate lifetime predictions.
