Machine element 2024 – The most important things in brief

Today’s trends in the development of machine elements include the use of advanced materials and manufacturing techniques such as additive manufacturing and high-performance plastics. Electronics are also making inroads, for example in the form of Sensors, so that the importance of condition monitoring and predictive maintenance for the individual machine element increases.

The smart rolling bearing or the profile rail guide with position measurement offer more intelligence in terms of Industry 4.0All these advances make it possible to develop lighter, more robust and more durable components that perform specific tasks and meet special requirements.

In addition, the digital transformation its general Calculation and selection of machine elements. It is actually a pity not to have to use the textbook on technical mechanics with the complex calculations or the Rohloff/Matek books as well as tables and formula collections from the mechanical engineering course anymore: With the help of Computer Aided Engineering (CAE) and Artificial intelligence Designers can carry out more precise simulations and optimizations than was ever possible before. This leads to more efficient and reliable designs. Printing thousand-page catalogs is also a thing of the past; configurators have long since taken over these tasks.

The Future of machine elements lies in the further integration of IoT and AI, which will significantly expand the functionality of advanced components in terms of predictive maintenance and self-optimizing systems. These technologies will significantly improve the service life and performance of machines and reduce operating costs. The challenge is to integrate these advanced technologies into existing systems while ensuring standards and compatibility.
