A review on self-adaptive design elements
摘要
Adaptive systems in engineering adjust their properties in response to changing conditions such as load, temperature, or speed. Many existing implementations achieve adaptability through mechatronic systems incorporating actuators, sensors, and control systems, which often result in increased complexity, weight, and reduced robustness.
To overcome these drawbacks, systems are increasingly explored that achieve adaptability solely through their structural design and material behavior. In this work, the term ‘self-adaptive’ is used for these systems to highlight that adaptation emerges inherently from the properties of the structural elements themselves, without any external control. This leads to simpler, lighter, and more robust solutions.
This review focuses on the principles and applications of self-adaptive design and machine elements, such as bearings, seals, couplings, springs, dampers, housings, gears and shafts. A classification of design elements will be presented, along with an explanation of self-adaptivity principles. Additionally, an overview of the state of the art for specific design elements will be provided, followed by current and future research directions.
