Xcite Systems Corporation is headquartered in Cincinnati, Ohio, located in the southwestern part of the state with offices located India, Japan, Korea, and China (Beijing, Chengdu, Shenzhen, Hong Kong, Shanghai, Shenyang, Wuhan, Xi’an). This company was founded in 1997 by former Zonic Corporation executives with the idea to create a company that consolidated technology and products focused on meeting the growing need for structural excitation for the aircraft and aerospace industries, the automotive industry, defense industry, machine tool industry, off road and construction equipment, power generation equipment, process and industrial products industries, railroad industry, shipbuilding industry, steel industries, university and research institutes, and consultants and test laboratories. It is a manufacturer of equipment which has developed and manufactured equipment that has met the needs of the industries listed above. Two such types of equipment developed and manufactured by this company are the Xcite 1200-9 Continuous Rotation Torsional Excitation System and electrodynamic shakers.

The XCite Systems Corporation is dedicated to serving the needs of the structural dynamist for high model excitation applications. The products sold by this company actually originated in the University of Cincinnati Mechanical Engineering Department as part of a research project to develop the means to predict and control machine tool chatter. As part of this research project the first Xcite 1100 System was developed. As Xcite Systems Corporation grew they developed and introduced new products to the commercial market. For example, this company produced the first commercial linear inertial mass exciter, the XCite 1100-5 Inertial Mass System, which allowed testing of structures such as missile silos, cooling towers, bridges, and large electrical stators objects for which there were no back up fixtures in place.

The Xcite 1200-9 Continuous Rotation Torsional Excitation System allows engineers to torsional excite structures that are rotating at speed up to 400 RPM. The frequency range of this system is 20 Hz to 300 Hz of stepped sine or random excitation which is completely independent from operation speed. This unique system allows engineer(s) testing the equipment to accurately measure both torsional and bending mode frequencies of steam turbine rotors and blades while under centrifugal loading of 3000 to 3600 RPM normal operation. This type of modal excitation system has been used in the development of diesel engine torsional dampers, turbine rotors, anti-locking brake systems, automobile axles, and half axles.

The XCite electrodynamic shakers are capable of creating both random and sine excitation. This type of equipment works between with when a structure in linear, of medium size, and medium damping. These systems are available in the force ranges from 10N to thousands, making them valid for medium structures with medium damping. Products that are good candidates for using this type of shaker include: motorcycle frames, complete electronic packages, and aircraft flight control services. The drawback of using this type of shaker is for modal excitation includes: limited static preload capacity and the large size of shakers with higher force capacities, for example a 10,000 shaker would be impossible to fixture in a machine tool or under an automobile.

Author Bio: Ellie Lewis recently met with an engineer who could explain the use of torsional excitation and its benefits. She searched the term electrodynamic shakers to learn more about it.
