Monitoring mechanical systems that are exposed to dynamic loads during operation requires a technical indicator that provides reliable information on degradation. In this paper, the damping ratio is used as an indicator and can be obtained from monitoring data such as acceleration. Its change from the initial value highly correlates with the system change that can lead to failure. The damping ratio can be relatively easily estimated from the free response data. Such events occur frequently for systems that are subjected to environmental loads such as wind gusts on structures, or sudden stops and changes in the operational cycle.

通过自举技术和贝叶斯分析进行自动阻尼估计，用于机械系统状态监测


监测运行期间承受动态负载的机械系统需要一个能够提供可靠的退化信息的技术指示器。本文以阻尼比作为指标，可以从加速度等监测数据中获得。它相对于初始值的变化与可能导致故障的系统变化高度相关。阻尼比可以从自由响应数据相对容易地估计。对于承受环境负荷（例如建筑物上的阵风或运行周期突然停止和变化）的系统来说，此类事件经常发生。
