Experimental Assessment of Noncontact Type Laser-Based Force Measurement Technique for Impulsive Loading

Force measurement is an essential element in the design of mechanical or nonmechanical systems. The choice of a particular technique, among the numerous measurement techniques available, depends on various parameters within which the nature of force is an important one. The measurement of impulse force is considered in this study using two techniques. In view of this, an experimental setup has been developed to understand the applicability and assessment of a laser-based extrusive technique, along with the established intrusive accelerometer-based technique for impulsive force measurement. The accelerometer-based measurements can be used to precisely predict the magnitude and temporal nature of the force. However, the velocity-based impulse prediction shows some limitation on complete representation of the system. In addition, the indirect measurement of acceleration from the velocity measured seems to have better prediction of the force.
