Technical requirements: Subject of the acquisition is the integrated solution for testing and modelling of mechanical systems.
Main part of the acquisition is a LMS SCADAS Mobile Frontend. It serves as a central unit for the measurement data acquisition and processing. It has a modular setup allowing to plug into the mainframe different acquisition modules dedicated to different sensing technology (cur-rent, voltage, charge etc). SCADAS mobile is at the same time the signal generator to facilitate control of the actuators exciting the tested object. We plan to use SCADAS mobile in the Multiple Input Multiple Output configuration. SCADAS allow for the future extension of the system through the connection of multiple mainframes. This is extremely relevant for measurement of the long span blades of wind turbines exceeding lengths of meters. SCADAS has also recorder functionality which allows to develop entire measurement campaign without interaction of the human operator. It can be programmed and put in the remote location (spinning hub of wind turbine in operation) collecting signals from the plugged sensors. SCADAS, through modular build is compatible with majority of the sensors available on the market for measuring mechanical, acoustic, flow and electric measurands. LMS SCADAS frontend is an industry standard and world class reference in the Noise Vibration Harness testing.
The LMS Test. Lab software suite governs the LMS SCADAS Mobile hardware. It complements the hardware capacity and covers entire scope of experimental approaches required by members of CASMaT — ranging from static, environmental, durability, acoustics, vibration and mechatronic testing including Hardware in the Loop and Model in the loop. LMS Test. Lab software has a modular structure. All the existing modules can be classified into 2 groups: data acquisition and signal processing and data post processing and analysis. There are dedicated modules for the vibration, environmental, noise, rotary machinery (angle domain analysis), video, GPS and durability. The licensing of the software is based on the Token concept. Each module uses a given number of tokens. We intent to purchase the license of NN Tokens which in practice will enable us to access any and every software module available.
Next to the LMS Test. Lab software the acquisition of the LMS Imagine. Lab Amesim system simulation software will be acquired. LMS Imagine Lab Amesim
LMS SCADAS Mobile Mainframe for the data acquisition together with integrated software LMS Test. Lab need the equipment which is not directly manufactured by Siemens Industry Software. We plan to acquire vibration acceleration triaxial transducers, force transducers with long cables, electrodynamic shakers and modal hammers for the structure excitation.
All above described items constitute the fully operational measurement system. Each single component can not provide the expected functionality and they have to be acquired and used together.
In the planned acquisition there is a built in Maintenance service regarding the hardware firmware and software updates. This service is also enabling the access to the Customer Service Helpdesk for active support in problem solving situations.
There are several important reasons for lack of reasonable alternatives to meet the technical and research requirements. These are:
— token based licensing LMS Test. Lab has a modular structure. Main module can be extended with dedicated acquisition and analysis modules. These modules are grouped with regard to a different applications domains, such as structural dynamics, acoustics, operational testing and durability. LMS Test. Lab offers a unique token based system for the module licensing. Pool of tokens can be used to activate dedicated software modules. This approach enables access to all the modules available,
— Simcenter modules share the same intercompatible data format ensuring seamless transfer of the analyses between testing and simulation,
— Simcenter platform enables development of the wind turbine blade digital twin. It comprises of the physical system connected to its numerical representation through a Siemens hardware and software.
It allows hybrid modelling to combine test and simulation models within one integrated environment being unparalleled functionality of the planned purchase.
LMS Test. Lab supports Strain Modal Analysis which enables the utilization of already deployed strain sensors for the estimation of the parameters of the modal model.
Low weight with high channel count. LMS SCADAS Mobile mainframe can include up to 120 channels at only 6 kg weight resulting with only 50 gram/channel compared to 250 gram/channel of competition. Planned research activities require low mass of system.
