Upcoming Events


Vibro/Dynamics is pleased to be exhibiting at several trade shows in 2019. Please come visit us! Our next trade show event is Railway Interchange in Minneapolis, MN. Railway Interchange – September 22nd-25th The Railway Interchange is a show for railway professionals. It is hosted by the Railway supply Institute (RSI), Railway Engineering-Maintenance Suppliers Association (REMSA), and Railway Systems suppliers Inc (RSSI). The Socitec Group supplies vibration and shock protection for containers carried by train, components mounted on rail cars, and equipment and buildings affected by nearby rail vibration.

Tuned Mass Dampers Using Wire Rope Isolators


Tall, steel, chimney stacks installed in windy regions are prone to violent vibrations that could lead to stack failure. The source of this vibration is due to the phenomenon called vortex shedding. Controlling the amplitude of vortex-induced vibrations is crucial to avoid catastrophic failure of the chimney and increase its lifespan. One widely accepted design for doing so is the use of hydraulic dampers installed between the top of the chimney and a steel ring. While this is an effective design at limiting a chimney’s vibration, it often requires maintenance, and its performance could vary based on temperature. A less known way of controlling chimney vibration is through the use of wire rope isolators (WRIs). When tuned to the proper stiffness and damping, WRIs can be very effective at controlling the chimney’s vibration. In addition, WRI-tuned mass dampers (TMDs) offer further advantages such as their maintenance free construction, temperature-independent performance, and extremely long lifetime. Our purpose here is to present a case study where the Socitec Group provided a WRI based TMD for a chimney stack. The simulation results show that just like hydraulic dampers, WRI TMDs can be very effective at controlling a chimney’s vibration.
