Vibration Test Applications on Environmental XPRT

Noise monitoring solutions for vibration testing

Vibration testing is is used for aerospace and defence testing, ground transportation, transport simulation, package testing, altitude simulation and more. Our comprehensive range of LDS electrodynamic shakers are designed for vibration testing of devices of any size - from a semiconductor component to a complete satellite system, to see how it will stand up to real-world conditions. With an LDS vibration test system your shaker, power amplifier, vibration controller and even environmental chamber are not only controlled from one PC, they run under one software package. Combined with data acquisition systems and analysis software suites, Brüel & Kjær ofers the complete vibration testing solution to establish proof of quality according to national and international standards, such as DIN, ISO, BS, MIL, IEC and ASTM.

Noise monitoring solutions for environmental noise and vibration

Environmental noise is unwanted sound and vibration coming from a plethora of sources, among them industrial plants, road and rail traffic, construction work, and aircraft. Add to these sports events, shooting ranges, leisure parks, etc, and you have noise from many different sources, each with different characteristics and posing specific problems for the professionals who have to assess them. The way the problems are dealt with differs immensely from country to country and is very much dependent on culture, economy and politics. We offer solutions to cover all demands from level checks to in-depth analysis, from measurement or prediction, to post-processing and reporting.

Noise monitoring solutions for Pass-by noise testing

Traditional Field Pass-by measurements are still the only way to certify a vehicle for exterior noise emission during operation, but Indoor Pass-by provides an extremely powerful and repeatable method of troubleshooting exterior vehicle noise in the controlled environment ofan anechoic chamber.

Pulsar noise testing equipment for workplace sector

Workplace noise monitoring is an interesting subject that can appear complex, but it is always worth remembering what you are trying to achieve. This can be summarised as: ““Minimising or avoiding the risk of noise-induced hearing loss in the workplace to comply with local, noise-based, legislation”” Such legislation is usually based on a European Directive that is then modified to suit the needs of each particular country. For example, in the United Kingdom, the ‘The Control of Noise at Work Regulations 2005’ are based on the European Union Directive 2003/10/EC; usually called “The physical agents (noise)” directive and expanded upon by the Health & Safety Executive.

Noise and vibration problem solutions for building & construction sector

Approved Document E of The Building Regulations (2003 Edition) is the document setting out the requirements for sound insulation in buildings. It contains a requirement that organisations carrying out sound insulation testing should be third party accredited in order to demonstrate their competence to carry out such work. We are registered under The Association of Noise Consultants scheme as a testing organisation.

Noise monitoring solutions for production testing

The word `quality` is generally used in connection with expensive items and luxury goods. Nowadays, the quality of their product is what suppliers and sub-suppliers live by. Customers, world over, demand and expect it. In manufacturing, much effort has gone into `engineering in` quality by carefully optimising the design and production methods. However, a variety of manufacture and assembly faults often result in unacceptable noise and vibration levels in manufactured products. There is still only one method that makes absolutely sure that every item coming off the production line fulfils expectations. That method is production line testing, where every unit produced gets checked as part of its production cycle.

Industrial solutions for structural health monitoring

Real time monitoring of structures is an excellent field of application for wireless sensor networks. ADVANTICSYS has provided solutions for the monitoring of structure in different fields, from bridges, where the vibration has to be controlled both in the construction and operation phase, to cultural heritage buildings with their structural integrity under risk.
