Durability Seminar Vibration engineers commonly collect acceleration and microphone data to manage noise and vibration - but what about ensuring product durability? HBM-nCode will present a free, one-day educational seminar held on September 28 at Briiel & Kja?r's Sound & Vibration conference held at The Westin in Southfield. MI. This seminar will provide a technical introduction to fatigue and durability analysis, broadening the scope of data collection past acceleration to investigate the additional benefits of collecting strain, load and torque. The combination of measured acceleration and strain data can provide powerful insight into product usage and structural behavior. Shaker tests are often used in the test lab for product validation and durability assessment. This raises a common question: what is an appropriate shaker profile that is equivalent to customer usage':' This seminar will also demonstrate how nCode software combines elements of vibration and durability analysis to define equivalent shaker profiles.

Custom Vibration Isolators Italy's National Institute of Nuclear Physics (INFN) has installed three custom vibration isolators for experiments within the Cryogenic Underground Observatory for Rare Events (CUORE), located within Cran Sasso mountain, the highest peak in the Apennines about 100 km (62 miles) from Rome. CUORE is a detector for neutrinoless double-beta decay and other rare events such as detection of dark matter like axions or weakly interacting massive particles (WIMPs). The new generation one-ton scale cryogenic detector will have a total mass of about 1.500 kg (3.300 pounds) and must be cooled to less than 10 mK (millikelvin) in a vibration-free environment. The cryostat is isolated bv a two-stage isolation system. The first stage mounted on low-frequency Minus-K isolators using patented NegativeStiffness Mechanisms. The second isolation stage is provided by regular springs at the top end of the suspension bars. "These isolators were not only made to perform at 0.5 Hz. but they had to withstand a seismic shock while under load." savs Dr. David Platus. inventor of Negative-Stiffness Mechanism vibration isolation. "The NSM isolators offer better isolation performance than air or active isolation systems." Collaborators on the CUORE project includes a consortium of members from UC Berkeley. UCLA, Livermore Lab, Berkeley Lab, Cal Poly, University of Wisconsin. University of South Carolina, University of Milan-Bicocca, University of Florence, Leiden University, University of Zaragoza. University of Rome. University of Genoa, University of Insubria, University of Padua, National Institute Nuclear Physics (INFN).
