Abstract:

With the growth of global energy demand and the rapid development of new energy technologies, the importance of energy storage technology is becoming increasingly prominent. Mechanical elastic energy storage technology, as a new type of energy storage method, has received widespread attention in recent years due to its advantages of high efficiency, environmental protection, and easy maintenance. This article provides an overview of the current research status of mechanical elastic energy storage technology, including advances in vortex spring materials, energy storage box structures, and operational control. Research has shown that the core component of mechanical elastic energy storage technology is the vortex spring, whose physical and mechanical properties directly affect the energy density and efficiency of the entire energy storage system. Meanwhile, the structural design of the energy storage box will have an impact on the entire energy storage system. In terms of operation control, the control strategy of permanent magnet synchronous motor (PMSM) and the development of key technologies such as decoupling control and intelligent control optimization were analyzed. In addition, the article also highlights the importance of optimizing the energy storage process, including precise control of motor operating status and optimization of vortex spring physical behavior. These studies provide useful ideas and references for the further development and application of mechanical elastic energy storage technology.
