Shock, Vibration & Noise News

Expenditures of time and money can be reduced in the process of developing electrical machinery design prototypes with this upgraded 3D software simulator. According to the vendor, the need for physical prototypes will no longer be necessary because the software analyzes possible vibrations that could cause oscillation. By using the software suite, the potential is there for designers to get their design right on the first try.

Vibration Testers help effectively maintain equipment. The Fluke 810 generates a diagnostic report of your machinery to save time and money. Combine with Thermal Imaging and you can see into the heart of your machinery and immediately identify the root cause of mechanical failure. Intrigued? Learn more!

Test Product International's 9070 Smart Vibration Meter: vibration analysis at the touch of a button. Analyze and interpret readings; incredible performance at an unbelievably low price. Overall machine and bearing conditions: vibration values are displayed with color coded alarm levels for ISO values and Bearing Damage (BDU). More info...

Convergence Instruments' Vibration Sentry RT 64/128 are an all-digital design with a three-axis integral MEMS accelerometer. They feature integrated oscilloscope and spectral analysis functions that can show the vibration signals in real time. They work standalone or USB connected.

The completely sealed weatherproof enclosure is small enough to be attached or embedded within the monitored equipment.

Since 1960, Kellett Enterprises, Inc., has been resolving vibration issues around the world. At first glance, many shake absorber pads look similar; but that's where the similarity ends. Not only do Kellett Enterprise customers receive the most efficient and quality-controlled effectiveness in any industry, they obtain the most advanced energy and cost-saving technology available.

These piezoresistive shock accelerometers measure motion over the long-term, with a 2,000 G measurement range. A critical damping feature reduces resonance amplification and minimizes shifting after a shock. The company claims that the sensors are drop-in replacements for older sensors that have two-hole screw mounting.

When a hospital in Australia installed diesel generators, the vibrating pains set in. The remedy was to install active vibration isolators that not only reduced vibration, but noise as well. A polymer sleeve placed on the springs of the isolation unit acts as a damper and helps reduce shock and vibrations caused each time the generators are turned on and off.

This USB-powered sound and vibration measurement module has a four-channel analog-to-digital converter, and each channel can sample at rates up to 52.7 kHz. Rather than using IEPE sensors to take measurements, IEPE conditioning is actually built into the analog circuitry of the module. Included is data acquisition software for analysis and display.

Two soundproofing compounds also reduce vibrations in a variety of structures. QuietGlue Pro is a damping compound that is applied to drywall to decrease sound transmission through walls and ceilings. QuietCoat is a sprayable viscoelastic polymer that can be applied to non-porous surfaces to drown out noise and dampen vibration.

Smooth operation and quiet comfort help boost perceived vehicle quality. Proven, effective NVH-control solutions from Dow Corning include noise-damping lubricants, UV-resistant adhesive and sealant assembly aids, and tough engineered elastomers for vibration-isolating rubber parts.

Wilcoxon Research received CE approval for the iT401 Alarm. The iT401 Alarm, which accepts any 4-20 mA loop powered signal and alarms based upon user-defined criteria, is now approved for sale in European countries recognizing CE mark approval.

The VIBRIUS vibration and motion monitoring system is suited for underwater vortex-induced vibration analysis. A control module calculates and stores data. Logging sensors collect data, which is then retrieved by an optical modem. The system relies on battery power for long-term use.

Series 9100 accelerometers enable portable calibration of sensors, vibration switches, and data collectors. Real-time sensor sensitivity is provided as the unit is designed for in-situ use. Up to 500 calibration records can be saved and copied to generate ISO 17025-compliant calibration certificates.

When comparing air-mounted gas springs to coil springs, the differences quickly become apparent. For example, compressed air inside the AirMount isolator enables lower static reflection rates than coil springs. And, the air springs tend to be more flexible and adjust better to load shifts to maintain a level surface, the writer claims.

No hands required. This piezoelectric sensor technology remotely monitors vibration stresses on machinery. Real-time updates and early warning signals alert users about impending failures. As predictive maintenance is put in place, downtime is reduced and productivity increased, claims the company.

CSZ Test Laboratory offers a variety of shock and vibration testing services for testing a wide range of products across many industries. Below is a list of our vibration and shock testing capabilities.

• Random, Sinusoidal, Mixed Mode
• Transportation and Packaging
• Gunfire, NAVMAT Screening, and more...

Vibration Specialty Corporation has remained the trusted leader in vibration analysis since our inception in 1918. Our staff members each have between 20-30 years of experience conducting vibration analysis and troubleshooting on every type of machinery. The industry experts turn to us when they cannot solve their machinery problems.

This ISO document, available now from IHS, specifies requirements that are necessary for a vibration measuring instrument to meet if inaccuracies of measurement made on the casing of machines, particularly when making repeated measurements for trend monitoring of a certain machine, are not to exceed a specific value.
