Description
Summary:Information for rotational Degree of Freedom (DOF) is automatically included in theoretical analyses of structures. It is also believed that rotational DOFs are of increasing importance for future applications. However, in current status they only play little role in dynamic testing for they are difficult to be measured in experiments. One main problem to be tackled is rotational motion measurement. This paper reports a novel Rotational Velocity Meter which can accurately measure rotational motion of elastic structures. Compared with conventional methods, besides high accuracy, this new sensor has advantages of simple structure, less local stiffening effect, less inertial loading, and point measurement.
