摘要
针对电梯轿厢系统受到的许多不确定因素的影响,如参数的结构不确定性和激励的随机性等,文中采取了一种创新的分析框架,该框架结合了随机性在系统参数及外部激励下的振动表现,实现了对系统振动性能的全面解析.通过运用先进的数学模型和计算技术,不仅对电梯轿厢系统在不同工况下的振动响应进行了详细拆解,还精确计算了系统对关键参数变化的敏感度,进而揭示了这些参数变化对系统整体振动行为的影响.该研究旨在通过深度分析轿厢振动响应及其灵敏度,为理解和优化高速电梯轿厢系统的振动性能提供新的视角和方法论.
Abstract
Since the elevator cabin system is affected by many uncertain factors during operation,such as structural uncer-tainty of parameters and randomness of excitation,in this article efforts are made to adopt an innovative analysis framework.It,in combination with the vibration performance of randomness influenced by system parameters and external excitation,has ensured a comprehensive analysis on the system's vibration performance.Some advanced mathematical models and computing techniques are used not only to conduct a detailed disassembly of the elevator cabin system's vibration response under different working con-ditions,but also to accurately calculate the system's sensitivity to changes in key parameters;as a result,the effect of these changes on the system's overall vibration behavior is revealed.This study aims to provide a new perspective and methodology for exploring and optimizing the vibration performance of high-speed elevator cabin systems through the in-depth analysis on the cab-in's vibration response and sensitivity.
