Acoustic-emission diagnostics and monitoring of transport and tribotechnical systems, research of dynamic constructions characteristics

Developments are designed for the purpose of creation new hardware and software methods for potentially risk objects diagnostics. Determination of acoustic parameters behavior for processed signals is considered to be the base for tests methodologies creation with assessment of complicated technical systems state and destruction prevention.

Processing of acoustic emission signal parameters is carried out. Diagnostics and monitoring technologies of concrete and bridge construction, high pressure elements and systems, technological products pipelines, components and structures of aerospace assignment, welding and solder junctions and other objects are developed based on acoustic emission processing in case of ongoing or step load.

Mobile systems with minimal electronic means use and extensive softwares use for management, control, measurement and information processing are developed. These mobile systems are characterized by significant amount of acoustic and emissions signals and their currents parameters, analysis of required amount of dimentionless assessments, determination of processes developed in products, their risk and influence into objects supporting capacity.  

Extensive software use for management, control, measurement and acoustic and emission information processing with receiving of significant amount of  acoustic emission parameters, analysis of required amount of dimentionless assessments with determination of risk for surface layers wearing-out processes  provide tests automatization in laboratory and industrial conditions with mobile acoustic and emission systems use.

Research of wearing-out, diagnostics, and monitoring processes of tribotechnical systems with prevention of their destruction is based on acoustic emission processing in case of short time and long-term load of friction units.

Developed system allows us to determine vibration parameters for large-dimensioned constructions: diagnostics and study of dynamic characteristics for large-dimensioned concrete and metal constructions, plastics, rubber based materials, etc. in industrial conditions and test samples in laboratory conditions using their dynamic load.

Flexible software control by measurement and processing processes of speed and vibration acceleration signals allows us to receive the complete parameters set. These parameters characterize dynamic behavior of the researched object, frequency of vibration, damping, dampings logarithm decrement, coefficient of mechanical losses, dynamic displacement, speed, acceleration, quality factor, etc. Parameters are determined on one-three channels for information recording vertical, horizontal, lateral vibration.
