Research

MDT Q2 is a research partner for universities and industries in the application of measurement techniques, instrumentations and computational mechanics. It includes modal analysis, operating deflection shape analysis, finite element analysis and virtual instrumentations.

 

Our challenge in R&D is to work on solution techniques that could explain the problems and their subsequent solutions in such a way that it could be easily understood by our clients, both engineers and management. Whatever sensors we use to trace the signatures of engineering parameters – accelerometers, proximity probes, strain gauges and others – and whatever subsequent data processing – time domain and frequency domain - we adopt, the challenge is to translate their behaviours into a universally accepted form called pictures - static or motion.     

 

"A Picture Is Worth A Thousand Words".  This is especially true when it comes to understanding some of the complex, dynamic problems that plaque operating machinery. A wide variety of animation techniques are available to accurately understand the appropriate solution to structural and mechanical difficulties. The ability to combine experimental and analytical procedures, encompassing both static and dynamic aspects, has proven to be invaluable in developing cost and time effective solutions and, as importantly, to present the solutions in the form easily understood by the whole spectrum of personnel associated with the problems.

 

Computer-aided Engineering utilizes mathematical technique for obtaining approximate numerical solution to the abstract equations of calculus that predict the response of physical systems subjected to external influences.  MDT-Q2 correlates these numerical methods (such as Finite Element Analysis) with frequency response functions (FRF) measurement techniques (such as FRF Modal and FRF Operating Deflection Shape Analysis) to diagnose complex machinery and structural problem by identifying dynamic weaknesses and simulating the actual on-site machinery condition and behavior. In effect, dynamic design modification and optimization can be performed in a virtual environment.

 

When performing measurements on complex domains and parameters, versatility in digital data processing and analysis is of a fundamental importance. Dedicated physical instrument tend to be rigid in its functionality and are limited by the instrument designer. Of course, options are available but it is still dictated by price and functionality. Virtual instrumentation provides a unifying approach (similar to the concept of element libraries in FEA) for the user to construct its own instrument that links together various digital processing stages. Modules from libraries for time domain operations, frequency domain operations, windowing functions, data reductions, statistical, arithmetic operations, controls, displays and storage, etc., can be arranged and linked with great flexibility; beginning from data acquisition stage right up to the display and storage stages. A single high-speed and high-bits data acquisition hardware linked to a normal PC with virtual instrumentation software is sufficient to substitute a range of highly priced physical dedicated instruments. MDT-Q2 conducts all its measurements using the concept of virtual instrumentation as it predicts the ‘not-a-distant-future’ demise of dedicated instruments.
