COMPUTER ANIMATION OF COMPLEX MODAL RESPONSE OF ONE, TWO-, AND THREE-DIMENSIONAL STRUCTURES

摘要

Complex mode vibration of structures is difficult to interpret from one or more static images. Animation is an effective means of visualizing complex mode vibrations. Methods of animating the dynamics of 1-D, 2-D, and 3-D models of structures are presented. A simple 1-D system was numerically fabricated to demonstrate the 1-D animation. Experimental data was collected with a scanning laser Doppler velocimeter to demonstrate the 2-D and 3-D animation techniques.
