Warsaw, April 2009

Operational Programme Innovative Economy

Priority axis 1: Research and development of modern technologies

Action 1.1:Scientific research support for knowledge - based

economy building

Warsaw, April 2009

Strategic aim of the project To improve competitivness of the Polish

economy through increasement in its innovative character and enhancement of modern technologies’ transfer in respect of practical application of modern systems of monitoring of technical state of construction and evaluation of its lifespan. In addition, the other aim of the Project is to introduce research results into the economy and to elaborate new unique techniques of SHM (Structural Heath Monitoring).

Warsaw, April 2009

Scientific and research aim of the project

• To develop technologies and systems of monitoring technical state of construction

• To elaborate methods of safety improvement and prolongation of constructions’ lifespan used in various economy branches (transport, power, building and chemical industries)

• To build monitoring systems of constructions’ state in order to alert in case of emergency in constructions where low risk level is required.

Systems’ projects submitted for realization1. Monitoring system of the state of rail vehicle - railway track elements. The system’s aim is to monitor condition of rail

vehicle and railway track.2. Dispersed monitoring system of large-size construction. The system’s aim is to monitor large-size and span

constructions.3 Monitoring system of buildings and engineering constructions of bridges and roads. The system’s aim is to monitor

technical condition of objects within road and bridge infrastructure. The monitoring includes short, large-surface and tall, diverse-shaped buildings, built in existing urban developments.

4. Monitoring and measurement system using incoherent optical methods. The system’s aim is to monitor a wide range of building objects (buildings, bridges, dams, halls etc.). The system also includes devices, its elements and

materials. 5. Monitoring and measurement system using selected coherent optical methods. The application of this system is similar to the application of the incoherent system.6. Monitoring system of the state of engineering constructions based on video measurements.The system’s elaboration

will enable non - contact measurements of constructions’ geometry, especially observation of changes in constructions’ distortion during exploitation.7. Monitoring system of construction with the use of vibro – thermography. The system’s elaboration will enable

continuous and periodical monitoring of constructions’ condition based on vibro – thermographic measurements. 8. Monitoring system of construction, with the use of modal filter. The system’s elaboration will serve as software system

compatible with any measurement set.9. Monitoring system of diagnosing of wind power plants’ rotor based on an active method of condition diagnosing

through provoking high frequency vibration effect. The Lamb wave system’s elaboration will enable diagnosing damages of power industry devices and renewable power engineering (wind power plant). 10. Monitoring system for construction with the use of impedance measurement. The system will be used to evaluate construction joints as well as cracking of critical elements.11. Dynamic Railway Scale (DKW). The system will enable weight and speed measurements for railway vehicles at full

speed.12. Dynamic Road Scale (DWD). The system will enable axle load and speed measurements for road vehicles at full speed13. TRANS – MONIT system will enable monitoring of technical condition of road and rail truss steel bridges. 14. ELGRID system will enable monitoring of cracking development in concrete structural elements.15. Damage identification system based on piezoelectric transducers. The system’s aim is to monitor technical condition

and damages of air construction elements and devices, renewable power engineering devices (eg. Rotor blades), building constructions (eg. halls, bridges), road transport means, elements (constructions) based on composite structures, etc. 1. Risk identification system based on signal measurements from FBG sensors transmitted through optical fibre. The application of this system is similar to the application of the system based on piezoelectric transducers.

Unified implementation procedure1. Method elaboration ( theoretical basis, literature research, elaboration

of applicability assumptions, sensitivity analysis of the method)2. Simulation testing of the method (building of the object model,

damages modelling, measurement system modelling, numerical simulation of the method)

3. Elaboration of assumption for construction of monitoring system and evaluation of construction condition ( elaboration of measurement system’s project - sensors, systems of signals’ collecting, converting and managing, elaboration of ‘evaluation state’ algorithm, elaboration of principles and procedures for calibration)

4. Making a prototype of monitoring and state evaluation system ( concerning software and equipment)5. Testing of system prototype at laboratory scale (system testing on

objects of known properties, verification and revision of the system)6. Testing of system prototype at industrial scale on real objects (system

installation on a real object and supervised exploitation)7. Promotion of elaborated monitoring system and evaluation of

construction condition ( publications, participations in fairs and presentations)
