Critical Application Technology of PIV in Dynamic Centrifugal Test and Design Method of Instrumentation

Abstract:

PIV is a velocity-measuring technology commonly applied for the measurement of deformation and displacement in the field of experimental fluid mechanics, but no previous report is found for the application of this technology in dynamic centrifugal tests. As soil is a type of complicated materials with mechanical properties closely tying with the stress condition it suffered, centrifugal shaker shows great superiority to the research of soil dynamics and geotechnical earthquake engineering. PIV capable of measuring deformation and displacement of any point at any time supplies overall visible information for full understanding of failure mechanism. For only the deformation of selected points captured by transducers in current instrumentation, the application of PIV in dynamic centrifugal tests is advantageous to understand the complex behavior of soil under earthquake and high-stress loading. This paper analyses the critical technology of PIV application in dynamic centrifugal tests and proposes the requirements of image acquisition system design as well as a method, which provide some guidance and reference for construction of centrifugal shaker.
