Before a new product goes into serial production it must undergo a series of standard tests in order to ensure no failure or malfunction will occur during the service-life. One of the tests is vibration testing, where the product is mounted on the electro-dynamical shaker and excited with the vibration profile that is reasonably more severe than the actual vibration load during the operation. Consequently, in modern engineering this brings up the need for a software tool that predicts the product's life under a given vibration loading in the design stage, before the first prototype is built. The CimFat plug-in for CATIA performs the product life estimation in the CATIA analysis environment with the state-of-the-art methods in the area of vibration fatigue.
Predicting the product's life under a vibration load is a complex challenge, since a number of different vibration loads and types of loading are used for the product testing. The CimFat plug-in for CATIA offers a simple and clear way to perform vibration fatigue analysis in form of the additional analysis case.
The benefits of the CimFat plug-in are:
- the time-to-failure prediction of a product for a given vibration load
- comparison of different designs with respect to the fatigue criteria
- avoid design changes in the prototyping or production stage due to the unexpected fatigue damage during the shaker-testing
- vibration fatigue calculation, integrated in the standard numerical analysis of the product
