Abstract

This paper discusses the application of a novel multiple coordinate vibration measurement technique. The technique can simultaneously measure three translational (x,y,z) and three rotational (Θx, Θy, Θz) displacements of a vibrating object. Th system is based on sensing the positions of three collimated light beams reflected from a tetrahedral target attached to the vibrating object. The dynamic position of the target is determined by using the system geometry, coordinate transformations and kinematic closure procedures. The paper will first briefly introduce the measurement concept. The paper will discuss the application of the measurement system for multiple coordinate vibration measurement. Experimental time and frequency domain data acquired from laboratory tests will be presented and discussed.
