This paper presents a technique for rapid diagnostics of structural integrity that exploits spectral sidebands measured by the continuous scanning LDV (CSLDV) measurement method. Structural integrity can be monitored by Operational Deflection Shapes ODSs, which can be quickly measurable at any excitation frequency when a laser continuously scans a vibrating surface. The LDV output time series is a...... hiện toàn bộ
Characterization of a Digital Image Correlation System for Dynamic Strain Measurements of Small Biological TissuesSpringer Science and Business Media LLC - Tập 40 - Trang 743-753 - 2016
E. Rizzuto, S. Carosio, Z. Del Prete
Digital image correlation (DIC) is an optical technique for contactless displacement and strain measurement recently applied to biological tissues. We characterized a DIC system for small biological specimens based on a high speed camera, a stereomicroscope, and an original image correlation algorithm. Optical features have been evaluated calculating the optical distortion and the modulation trans...... hiện toàn bộ

Study of the effects on turbocharger performance generated by the presence of foreign objects at the compressor intakeSpringer Science and Business Media LLC - Tập 37 - Trang 30-40 - 2017

The study performed on this work consists of evaluating the consequences of the introduction of various foreign objects at the compressor inlet of a turbocharger. The most plausible objects were selected. A specific test bench was set up in order to perform the experiment and measure the compression ratio and compressor efficiency evolution. Measurements were performed before (healthy compressor) ...... hiện toàn bộ
