It is becoming more and more important to assess fatigue life in the early stages of developing vehicle engines in particular for the development of transmissions. winLIFE has the necessary calculation methods for analyzing fatigue life. These can be linked to equipment for recording measured data and used for simulating the drive train. Actual driving cycles can be measured for very different conditions. Using this data as a basis, simulations can be carried out to calculate the dynamic values in the power train (revolutions and torque). In this way it is possible to determine the fatigue life of individual components for each driving cycle. Total driving cycles for the life cycle of a vehicle can be obtained by adding together individual driving cycles. By combining individual driving cycles to such a total driving cycle, it is possible to make a fatigue life prognosis. This method is transparent since the critical conditions for a component can be recognized in individual stretches of the journey. We describe this as a critical component collective. It is possible to establish a system for optimizing fatigue life and reliability which enables you to use this method over a long period of time. This leads to a shortened development phase and improved reliability.
