摘要: 电梯安全是当今人们普遍关心的问题。电梯应急辅助装置的发展经历了从依赖机械保护装置到冗余驱动与蓄能制动协同的主动安全技术转变。近年来，随着科技的快速发展，基于冗余驱动与蓄能制动的高速曳引电梯应急辅助装置展现出巨大优势，显著提升了高速条件下电梯的平稳制动。为确保装置在极端工况下的可靠性，文章引入热–力–动态多物理场耦合仿真分析，并建立包含台架试验、故障注入测试与加速寿命试验的评估体系，结合失效模式与效应分析FMEA与可靠性指标形成完整的可靠性论证框架。当前该技术的推广仍面临实际验证不足、长期数据缺乏等挑战，未来需进一步优化现场部署和监测，建立标准测试规范，推动该技术在高速电梯安全领域的工程应用。

Abstract: Elevator safety remains a matter of widespread public concern today. The evolution of emergency auxiliary devices for lifts has transitioned from reliance on mechanical protective mechanisms to active safety technologies integrating redundant drives with energy-storage braking systems. In recent years, rapid technological advancements have demonstrated the significant advantages of high-speed traction lift emergency auxiliary devices based on redundant drives and energy-storage braking, markedly enhancing stable braking performance under high-speed conditions. To ensure the reliability of these systems under extreme operating conditions, this paper introduces thermo-mechanical-dynamic multiphysics coupled simulation analysis. An evaluation framework incorporating bench testing, fault injection testing, and accelerated life testing is established. This is combined with Failure Mode and Effects Analysis (FMEA) and reliability metrics to form a comprehensive reliability assessment framework. Currently, the adoption of this technology faces challenges, including insufficient practical validation and a lack of long-term data. Future efforts should focus on optimizing field deployment and monitoring, establishing standardized testing protocols, and advancing its engineering application within high-speed lift safety systems.
