In high-speed and high-precision machinery, trajectories with high-frequency harmonic content are one of the main sources of reduction of operational precision. Trajectories with high-frequency harmonic content generally demand even higher-harmonic a

In micro-line segments machining, transition curves with high harmonic components are more prone to causing vibration issues in the feed drive system, which affects machining efficiency and quality severely. To construct low harmonic trajectories, th

Because micro-line segments are the most widely used form of tool-paths for computer numerical control machining, the smoothness at the junction of two adjacent segments is still the bottleneck for...

Smart Structures and NDE for Industry 4.0.
Currently available methods and systems for testing components for survival and performance under shock loading suffer from several shortcomings for use to simulate high-G acceleration events with relatively long duration. Such events include most mu

Novel piezoelectric-based self-powered impulse detecting switches are presented. The switches are designed to detect shock loading events resulting in acceleration or deceleration above prescribed levels and durations. The prescribed acceleration lev

In time critical power up applications, such as pre-launch preparation of smart munitions, both power and guidance information needs to be transferred rapidly from the host to the munitions. Tethered solutions are not practical and the existing magne

The process of harvesting mechanical energy from the environment and converting it to usable electrical energy can be illustrated as shown in the block diagram of Fig. 2.1. The input mechanical energy to be converted to electrical energy may be in th
