摘　　要：为了将可恢复功能防震理论引入“工程结构抗震”课程,该文基于耗能低和自复位能力良好的受压碟形弹簧,设计了一种碟形弹簧实验装置,并对该装置的滞回曲线、骨架曲线、耗能能力和自复位能力开展试验研究,揭示碟形弹簧的力学性能与工作机理等。该文将疲劳试验机引入工程结构抗震课程与实验教学,使学生能从宏观和微观视角直接认识碟形弹簧的耗能演化特征,以及认识碟形弹簧在地震作用下的耗能与复位性能。该实验可用于锻炼学生硬件操作和软件使用能力,以问题为导向对结果进行数据处理和分析,加深学生对工程结构抗震原理和可恢复功能理念中自复位、可更换和耗能机制的理解,培养学生的探索精神和实际操作能力。[Objective]This paper incorporates the theory of seismic resilience with recoverable functions into the“Engineering Structure Seismic Resistance”course by focusing on compression disk springs,known for their excellent energy dissipation and self-resetting capabilities.By designing an experimental device for disk springs and research conducted using a servo fatigue testing machine,the mechanical properties of recoverable functional structures are thoroughly examined.The“Engineering Structure Seismic Resistance”course is a fundamental subject in structural engineering.Integrating the concept of recoverable functions enhances students’understanding of engineering seismic resistance.By integrating the fatigue testing machine into seismic resistance experiments and effectively utilizing teaching platforms,students can directly perceive the energy dissipation evolution characteristics of disk springs from both macroscopic and microscopic perspectives and profoundly understand the energy dissipation and resetting performance of disk springs under seismic actions.[Methods]The disk spring,also known as the“Belleville spring washer,”features a conical feature along its axis.It can bear loads and store energy through deformation under loading.Disk springs can be combined in three main ways:series,parallel,or compound configuration.These combination methods expand their application scope,allowing different setups to suit specific engineering projects.The disk spring device designed in this study utilizes the compression mechanism of disk springs and optimizes the device to keep the springs compressed at all times,fully utilizing their compression effect.The experiments will conduct tests and investigate the hysteresis curve,skeleton curve,energy dissipation capacity.and self-resetting capacity of the device.These tests will be performed using four key variables:types of disk springs,preloading height,combination methods,and modularized areas of the device.These findings aim to reveal the mechanical properties a
