Description
This presentation explores an example of advanced condition monitoring in non-stationary operating conditions, focusing on the demanding requirements of motorsport testing applications. As a foundation for this presentation, we’re focusing on the challenges in developing a highly dynamic e-motor for gearbox testing. The critical challenge lies in achieving low inertia designs for the e-motor, which, in turn, leads to elevated electrical and mechanical stresses within the structure.
Addressing these challenges necessitates the identification of various required measurements to detect potential design issues and mechanical failures at their earliest stages. To this end, a comprehensive system layout for condition monitoring is presented, including the hardware components, such as IO channels and sensors, that are integral to the monitoring process.
As a technical detail, an algorithm is presented, which offers a solution for the early detection of changes in high-frequency signals. This algorithm is a crucial part of the presented monitoring system, enhancing the ability to proactively assess the motor’s health and performance in real time. By leveraging this combination of innovative hardware and sophisticated signal processing, motorsport teams can gain a competitive advantage by identifying and addressing issues before they result in costly breakdowns, ultimately improving the reliability and efficiency of their gearbox testing operations.
Learning Takeaways:
- Gaining insight into the challenges of condition monitoring in highly non-stationary environments
- Providing a holistic layout for machine monitoring
- Creating awareness of the trade between reliability and condition monitoring costs
