Schrey & Veit - Shock and Vibration Technology

Schrey & Veit GmbH specialise in the fields of vibration technology. Our team has years of experience in shock and vibration isolation, vibration absorbing and acoustic and production engineering in the aviation and aerospace, car, military and railway industries.

For vibration absorption and noise control on railway vehicles we took over the department INCT from DaimlerChrysler Aerospace in 1995. The absorbers developed and patented by INCT will be used on wheels of railways, from the ICE up to tramways, in gearboxes, on curved and tangent tracks, steel bridges as well as for general engineering, ship building and the car industry.

The manufacture of prototypes and our well equiped laboratory guarantee a very fast and low cost development of our products.

HIGH PERFORMANCE – LOW COSTS

We place great value on adapting our products to "real life conditions".

To prove the acoustic effectiveness of our products we offer measurements in cooperation with a special office of acoustics.

WHEEL VIBRATION ABSORBER

The wheel absorbers VICON-RASA are suitable for resilient and monoblock wheels of all wheelset manufacturers with different mounting types. They reduce rolling and squealing noise very effectively. The absorbers developed and manufactured by S&V have been in practical operation since 1995 in over 3,000 wheels of different vehicles like trams, coaches and locomotives.

RAIL VIBRATION ABSORBER

The rail vibration absorbers VICON-AMSA are suitable for all sizes of rails at ballast and ballastless tracks. Due to this new and simple construction of the rail absorbers, a very efficient reduction of structure borne noise radiation of the rail was achieved. The reduction of rolling and squealing noise has been demonstrated in operation. Because of the universal way the absorbers are built, they can be mounted on rails very quickly without closing the line and independently from environmental influences as well as without special pretreatment of the rails.

VIBRATION ABSORBER FOR STEEL BRIDGES

From a series of the rail vibration absorber, S&V developed an absorber system by doing a lot of modifications. With the new absorbers on a bridge structure in combination with absorbers on the rail, a noise level reduction of 6 dB was measured. This project was done in cooperation with the BMVIT, the ÖBB and the community of Vienna on a 90-meter long railway steel bridge.

STANDARD PRODUCTS

For applications where standard products (Rubber-metal parts, cable mounts, etc.) are sufficient, we work together with producers who come up with essential requirements on quality and price.
