| Abstract: | Laser electronic speckle technology plus phase-shift has the features of overall display,non-contact,high sensitive and precision,etc.So it can be widely used in analyzing the strength and stiffness of parts in diesel engine.The technology was applied in measurement research of 3-D displacement of diesel engine's fuel pump.And phase-shift technology was used to get data of 3-D displacement of fuel pump's model under pressure.The data were compared with FEM results,which show a relative error less than 5%.ESPI provides a convenient,fast,effective,and brand new design and test method. |
