Outline of Final Research Achievements

This research treats not only the static surface flexible shape measurement of space membrane structures and large deployable structures, but also deployment behaviors and dynamic surface behaviors, and the shape and the deformation are shown in three-dimensional data. This research issues and the method have been verified through the cooperative experiment by the proposers. The principle of the proposed measurement method was confirmed to static shape of measurement objects. The proposed method is composed of the grating projection method as a non-contact surface shape measurement and the three-dimensional matching technique, and so by this composition, the method can be extensible to large structures irrespective of the object size. The noteworthy achievement is that the surface wave propagation of flexible membrane structural component was measured and also visualized by the vibration measurement using a grating projection method.
