CMSSHM
Structural Health Monitoring Software
Structural Health Monitoring software (CMSSHM) is a plugin to our standard Condition Monitoring Software, which enables the continuous measurement and recording of raw data. The software also postprocesses the data to give a continuous on-line record of the condition of towers and sub-structures.
The system comprises measurement hardware as well as the CMSSTD software. At the simplest level, the system can operate from a single 2D MEMS Acceleratio Sensor. However a much more detailed assessment can be built by incorporating a range of different sensor types measuring at various levels and locations within the support structure (tower, transition piece and foundation).
The data acquired at a limited number of measurement points are transferred into a comprehensive finite element model of the entire structure. The results can be provided in a digital twin that derives the structure’s motion, loads, and natural frequencies from a continuous live data stream.
Rainflow counting and damage equivalent loads are used to assess ongoing fatigue damage to the structure. Through comparison with particular damaging events (e.g. storms) and operating conditions future operation can be optimized.
Knowledge of structural aging also enables a targeted inspection strategy. This allows for extended intervals between routine inspections for structures that have not experienced any relevant damage events.
This gives a mechanism for plant protection and lifetime extension, which can be applied with minimum effort and integrated with other condition monitoring functions.
Bachmann provides standard systems for structural health monitoring (SHM). The results generated by CMSSHM can be integrated with CMS and SCADA data to create a comprehensive and value-rich data foundation. Sensors and systems from third-party vendors can also be incorporated.
