An important cause of failure in machines with complex components is fatigue from vibration due to being subject to multiple forces that vary over time.
While these machines undergo extensive testing both at the bench and in the field, engineers need a generalized methodology to better calculate the fatigue in the presence of any number of known loads in time for a given cycle, in order to improve the estimation of the components’ fatigue life and effectively integrate that into the product development process.
This technical article details the application of the methodology developed using ANSYS WorkBench.

The development of medical devices presents unique technical, regulatory, and economic challenges, requiring a multidisciplinary approach to ensure patient safety, reliability, and market competitiveness. Medical devices span a wide spectrum—from drug delivery systems to surgical robots—and must meet stringent functional, material, and regulatory requirements. A critical and often underestimated factor influencing their performance and manufacturability is mechanical variation, the inevitable deviation from nominal design that occurs during production.
