ABSTRACT Vibration generated by use of masonry equipment can be a threat to wall paintings. Its assessment, mitigation and control is of critical importance to risk management and the safeguarding of works of art, particularly those which are immovable. The planned programme of window restoration in the Royal Gallery, Palace of Westminster, started in 2016, directly above the monumental wall painting of Trafalgar, had the potential to cause serious damage to this painting. For a period of 18 months the Curator’s Office worked with stakeholders, conservation scientists, conservators and stone masons to minimise risk. The project developed a monitoring strategy, set vibration thresholds, managed risk and negotiated the use of tools and working methods. To assess vibration data loggers equipped with 3-axis acceleration sensors were installed at critical locations. To corroborate these findings assessment was undertaken using a sound level analyser. This assessed acceleration at a series of frequencies in the 0–100 Hz range considered most damaging to artworks. However, a critical component was conservator-led in situ monitoring of vibration. When necessary, this live monitoring allowed conservators to dynamically assess and negotiate the adaptation of tools and techniques to reduce levels. This real-time approach proved essential in understanding peaks and changes in levels of vibration; informing discussion between stakeholders, ensuring monitoring translated into effective preservation.

Daniel Maclise 的壁画 Trafalgar 的振动监测

摘要 使用砌体设备产生的振动可能对壁画构成威胁。它的评估、缓解和控制对于风险管理和保护艺术品，尤其是那些不可移动的艺术品至关重要。威斯敏斯特宫皇家美术馆的窗户修复计划于 2016 年开始，位于特拉法加纪念性壁画的正上方，有可能对这幅画造成严重损坏。在 18 个月的时间里，策展人办公室与利益相关者、保护科学家、保护人员和石匠合作，以尽量减少风险。该项目制定了监控策略、设置振动阈值、管理风险并协商使用工具和工作方法。为了评估振动数据记录器，配备了 3 轴加速度传感器，安装在关键位置。为了证实这些发现，使用声级分析仪进行了评估。这评估了 0-100 Hz 范围内一系列频率的加速度，被认为对艺术品最具破坏性。然而，一个关键组件是由保护人员主导的现场振动监测。必要时，这种实时监控允许保护人员动态评估和协商工具和技术的适应性以降低水平。事实证明，这种实时方法对于了解振动水平的峰值和变化至关重要；为利益相关者之间的讨论提供信息，确保监测转化为有效的保护。这评估了 0-100 Hz 范围内一系列频率的加速度，被认为对艺术品最具破坏性。然而，一个关键组件是由保护人员主导的现场振动监测。必要时，这种实时监控允许保护人员动态评估和协商工具和技术的适应性以降低水平。事实证明，这种实时方法对于了解振动水平的峰值和变化至关重要；为利益相关者之间的讨论提供信息，确保监测转化为有效的保护。这评估了 0-100 Hz 范围内一系列频率的加速度，被认为对艺术品最具破坏性。然而，一个关键组件是由保护人员主导的现场振动监测。必要时，这种实时监控允许保护人员动态评估和协商工具和技术的适应性以降低水平。事实证明，这种实时方法对于了解振动水平的峰值和变化至关重要；为利益相关者之间的讨论提供信息，确保监测转化为有效的保护。这种实时监控使保护人员能够动态评估和协商调整工具和技术以降低水平。事实证明，这种实时方法对于了解振动水平的峰值和变化至关重要；为利益相关者之间的讨论提供信息，确保监测转化为有效的保护。这种实时监控使保护人员能够动态评估和协商调整工具和技术以降低水平。事实证明，这种实时方法对于了解振动水平的峰值和变化至关重要；为利益相关者之间的讨论提供信息，确保监测转化为有效的保护。
