Recent advances in correlation and integration between vibration control, energy harvesting and monitoring

Traditional structures adopt a split design with vibration control, energy harvesting and monitoring, which is difficult to meet the needs of technological development. The development of new structure from a single function to a multifunctional integration structure requires that the structure not only has the characteristics of low-frequency vibration control and energy harvesting, but also takes into account functions such as sensing, fault diagnosis and health monitoring. Given the continuously growing trend of multifunctional integration research, this paper presents the latest review on multifunctional integration of nonlinear vibration control, energy harvesting and monitoring. This is an interdisciplinary topic related to structural dynamics, mechanical design and power electronics, which has great prospects in various potential applications. The nonlinear design of new multifunctional integration structure is an essential step in the development of vibration control and energy harvesting, and is one of the most effective technical means to improve performance in low-frequency excitation environments. Therefore, the main implementation methods of nonlinear vibration control are discussed in detail. Subsequently, different strategies for nonlinear vibration energy harvesting and the challenges faced by wireless sensor network monitoring are described. On this basis, the research status, engineering applications and research trends of multifunctional integration structure are introduced in detail.
