The proposed research aims to support the realisation of a new non-contact smart conveying technology using squeeze-film phenomenon to levitate and move objects. The research is focused on development of mechanisms for controlled transportation of the levitated load with the aim to create solutions for industrial level applications.
The development for industrial level applications requires an in depth understanding of the underlying fundamental mechanisms, the optimisation of potential effects and development of control over conveyance.
The research aims at providing new designs for systems enabling contactless conveying with low energy consumption, thus fitting the research priorities of smart manufacturing technologies supported by the UK technology themes Manufacturing the Future and New Industrial Systems. The research is expected to have considerable economic impact for industries where the non-contact transportation is a fundamental aspect of the process.
The research project will develop different embodiments to generate the squeeze-film mechanism based on the idea of a “flexible structure” and containing “elastic hinges” enabling deformation of the structural frame to create a converging gap. Usually, one surface will perform high-frequency harmonic oscillations along the axis perpendicular to the system surfaces, perturbing the air and creating over a cycle of vibration a time-average repulsive normal force.
Understanding the coupled structural local deformations and the associated fluid mechanics represents the basis for development of control of the system and realisation of transportation of the increased levitated loads represent the main objectives of this research program.
The research project involves designing the experimental rigs and developing the numerical models combining methods used in acoustic analysis and fluid structure interaction. The analysis of correlation between analytical and experimental results will support elaborating design rules for the squeeze-film levitation system solution and refining the performances of such systems.
The proposed research program will support the development of smart, high precision contactless manipulation/positioning systems and significantly contribute to future UK economic development in the field of ultra-high precision engineering.
