Web2 Nov 2024 · In this study, a split–Hopkinson pressure bar (SHPB) is used for the shock mitigation analysis of polyurethane. The conventional SHPB consists of a striker bar, an incident bar, and a transmitted bar made of maraging steel as shown in Fig. 2.For soft materials, such as polyurethane having low stiffness and low wave speed, necessary … Cameras on remote operated vehiclesoften face issues with excessive vibration. These devices are typically not designed with isolators, but as the performance of today’s compact cameras continues to increase, vibration from surroundings is increasingly evident in output video. Getting smooth video and … See more In industrial applications, shock and vibration is everywhere. It degrades overall safety, efficiency, and machine output. Many times, equipment operators react to shock and vibration problems by seeking and integrating … See more Needing shock absorption is not sign of bad engineering. As mentioned, a common misconception is that shock absorption is no more than a Band-Aid solution to address fundamental … See more As with vibration mitigation, vibration isolation can also be misconstrued as an afterthought, rather than a proactive solution. Operators generally believe that if equipment needs to … See more
