自发电装置的建模、仿真与设计优化

Modeling, simulation and design optimization of self-generating device

近年来,自发电装置在生产生活中得到广泛应用,结构形式多样。基于大学生科技创新训练计划、毕业设计、实验室开放项目等实践活动,通过调研及实验室拆解,总结了现有自发电装置的结构形式及应用方向。建立了不同结构自发电装置的有限元分析模型,对自发电过程进行了模拟,总结了不同结构自发电装置产品设计的优缺点。为减少簧片、撞击等对自发电装置结构可靠性产生的影响,分别提出了旋转按压式、“跷板”式自发电装置并取得了有效的结果。通过项目实施也为大学生实践创新、提升复杂工程问题解决能力提供了参考途径。

In recent years,self-generating devices have been widely used in production and life with various structural forms.Based on the practical activities of Science and Technology Innovation Training Program,graduation projects,and laboratory open projects,this paper summarizes the structural forms and application directions of existing self-generating devices through research and laboratory dismantling.The finite element analysis models of self-generating devices with different structures are established,and the process of self-generating is simulated.The correctness of the simulation results is verified by experiments.The advantages and disadvantages of product designs of self-generating devices with different structures are compared.Further,in order to reduce the influence of reeds,impacts,etc.,on the structural reliability of the self-generating device,rotary-pressing and“rocker”self-generating devices have been proposed respectively,and beneficial results have been achieved.Through the implementation of this project,it also provides a reference way for college students to practice innovation and improve their ability to solve complex engineering problems.
