Vibration

Consulting, Testing, Analysis

Acentech assists in the design and analysis of facilities that accommodate extremely vibration-sensitive apparatus. Our industrial vibration consultants also work with equipment and structures that require high resistance to vibration-related damage or malfunction. Acentech's state-of-the-art instrumentation and signal processing techniques assure precise evaluation of vibration problems and characterization of indoor and outdoor dynamic environments. Acentech's noise and vibration consulting services include:

• Vibration analysis and design
• Vibration testing
• Design and acceptance criteria
• Surveys and specialized measurements
• Mitigation analysis and design
• Environmental assessment
• Diagnostics and problem resolution
• Structure-borne sound analysis
• Noise and vibration control
• Structural motions -- equipment, human activities, sound, wind
• Machinery diagnostics
  

We are instrumental in environmental assessment and mitigation design for transportation systems, heavy industrial plants, and mechanical equipment in large buildings. Acentech's industrial vibration and structural dynamics expertise has been applied to more than two hundred microelectronics, biomedical, optical facilities, and specialized installations for the National Institute for Standards and Technology, NASA, the National High Magnetic Field Laboratory, and major universities.

Remote Monitoring of Vibration and Noise

• Monitor construction noise and vibration in real time
• Protect highly sensitive equipment and/or operations
• Mitigate community annoyance

Concerns regarding construction noise and vibration are generally related to community annoyance and potential damage to nearby buildings. However, when nearby buildings house highly sensitive equipment and/or operations (such as hospitals, research facilities, and performing arts venues), construction vibration can cause adverse impact at levels far below those traditionally associated with building damage. Sufficiently severe vibrations can cause significant disturbance or, in extreme cases, cause the facility to shutdown vibration-sensitive operations. In these instances, typical construction monitoring programs are generally not sensitive enough to measure low-level vibrations that are vital to these situations.

Acentech's remote monitoring systems provide administrators, managers, contractors and researchers with real-time notification and continuous access to critical vibration and noise information. Using an internet connection, monitors can not only be viewed, controlled and downloaded remotely, but can send email and text alarm messages when pre-set limits are exceeded. These capabilities allow interested parties to anticipate problems, mitigate activities, schedule operations and document potential impacts and events.

Machinery Diagnostics

The RH Lyon Division of Acentech designs and develops advanced diagnostic systems for a wide variety of developmental and industrial applications, including machine condition monitoring and production-line quality assurance systems. Services include:

• In-process product evaluation
• Performance process data acquisition and analysis
• Performance improvement
• Signal processing and analysis
• SignaTrackTM system architecture
• Production quality assurance

When a machine operates, forces are created that result in vibration and sound. Properly sensed, processed and analyzed, these signals can provide a wide array of useful performance data to determine the "health" of the machine, to control its operations and make it run more efficiently, or to make design or quality control decisions that either improve product performance or eliminate manufacturing problems in a timely way.
