Frequently Asked Questions
What provisions are included for lifting the shaker?
Heavy duty eye bolts or lifting ears are attached to the shaker body. Straps or chains capable of supporting the weight of the shaker are attached to the eye bolts or lifting ears. A forklift hoists the shaker up by the straps or chains and gently moves and lowers the shaker into place.
How do we deal with the noise issue?
Electrodynamic shakers are extremely loud. Under the right conditions, the vibration system can sound like a jet engine ready for take off. They should be housed in an enclosure that has very good absorbing qualities. If the shaker is combined with a chamber, the space below the chamber can be enclosed with sound absorbing panels. Baffled air inlet ducts must be incorporated to supply the required flow of cooling air.
Where should the control console and amplifier be located?
The control and amplifier should be located in a quiet area. Some installations have separate, dedicated control rooms for this equipment, while others simply locate the controls outside the deadened booth. In the case of a combined environment facility, the amplifier and control instrumentation can be located next to the chamber if the area is large enough.
What networking connections need to be made?
Shaker controls have become quite sophisticated. They can be run as stand-alone devices or be connected to a local area network via Ethernet. They can also be remotely accessed via the internet if so desired. PCs used to drive the control algorithms are available with multiple USB connections that will support peripheral appliances that will enhance data transfer and storage as well as other test and measurement instruments.
Where should the cooling blower be located?
In a normal installation, the blower is mounted in a remote outdoor location, say on the roof of the building. The cooling air is drawn through the shaker body and ducted out of the building. The warm air can be diverted back into the building during cold months and used as a heat source. Some blowers are mounted inside the building. In this case, a quiet package or sound deadening enclosure built around the encloure should be considered.
Do we need a special floor that will support the weight of the shaker and eliminate vibration transmission?
Many low and medium force shakers feature vibration isolation systems that prevent energy from being transmitted directly into the facility floor. It is not uncommon for a shaker's mass to exceed 6,000 lbm (2,700 kg). A mass of 10,000 lbm (4,500 kg) or more can be expected if a concrete filled granite topped sliptable is included.
Should the shaker roll or be stationary?
If the shaker is used strictly for vibration testing at ambient conditions, it should be left in a stationary configuration. When combined with a chamber, consideration has to be given to whether to move the shaker or the chamber for product loading. The installation can be configured either way, but it is more common to move the shaker.
What is the best way to move a shaker around?
Some shakers have v-groove casters and mating sections of reinforced steel track that allow them to be moved back and forth (usually into and out from under a test chamber). An automated power tow can greatly ease the rolling around of shakers. Shakers are also available with an air glide transport system that permits the equipment to be easily maneuvered on a cushion of compressed air.
