Most types of industrial plant, manufacturing machinery and building services equipment generate high levels of noise and vibration; which typically will result in impact, airborne and structure-borne noise nuisance. If left untreated, these high levels of noise and vibration can become a health and safety concern for people working in the immediate location, or in adjacent offices and buildings.
The long term degenerative effects of high levels of vibration on machinery are also a concern and can commonly be the cause of frequent breakdowns, expensive part replacement and loss of valuable production time.
CDM Stravitec offers a wide range of high performance industrial noise and vibration solutions from our offices located throughout the world. Because there are many variables in size, type and functionality of machinery and equipment the vast majority of CDM Stravitec’s industrial solutions are bespoke; although we do also offer a range of systems for more standard applications.
CDM Stravitec’s many years experience in the industrial market, highly skilled engineering team and sophisticated computer analysis software enables us to design solutions for even the most complex industrial noise and vibration application.
Our standard systems are divided into two categories and following is a brief overview for each of them.
Base Isolation Systems
The dynamic parts of large industrial machines will inevitably generate noise and vibration and, as they are usually mechanically secured to the supporting structure, high levels of structure- borne noise and vibration are likely. The introduction of isolation (either directly under the machine or using an inertia base) between the machine and its supporting structure is a very effective method of controlling the noise and vibration and has been successfully used in many different applications.
Every new building will have mechanical equipment and a large quantity of pipes and ductwork which need to be suspended from the structure above. These building services produce noise and vibrations that travel into the building via the mechanical fixings which secure them. Providing suspension elements that effectively isolate the noise and vibration will significantly reduce the amount of structureborne noise and vibration transmitted into the building.
Typical examples of where our industrial solutions can be used to minimise the effects of noise and vibration from machinery:
As modern cities become increasingly high-rise, buildings require faster more efficient elevators to transport users over higher distances. Every lift has a machine room either pulling or pushing the lift and the machinery within these rooms may require isolation to avoid disturbance to nearby occupants. There is also likely to be a further requirement to isolate the running rails of the lifts to decouple them from the supporting structure in order to minimise structure-borne noise: Stravimech ElevatorFix.
The 50Hz hum and harmonics are characteristics of all transformers and this heavily tonal noise and vibration requires careful isolation to ensure it is not audible above background noise levels in nearby sensitive spaces.
Special design Stravimech Bearing are developed for transformers.
Weaving Machines, Metal Presses or Others
Metal and other kinds of material presses exert large impact forces during the production process of various finished products. Industrial textile machinery has advanced significantly over the past few decades and weaving looms are now enormous machines that generate large amounts of vibration and noise. A very successful method of isolation is to locate these machines on large concrete inertia bases to prevent the vibrations disturbing nearby areas and to protect the machine from damage.
