Companies in the United States are shedding more jobs, pushing the country’s unemployment rate to a 26-year high of 9.8%.

The US Labor Department said on Friday that employers cut 263,000 jobs in September, with companies in the service industries — including banks, restaurants and retailers — hit especially hard. This is the 21st consecutive month of job losses in the country.

The United States has now lost 7.2 million jobs since the recession officially began in December 2007. The new data has sparked fears that unemployment could threaten an economic recovery. Top US officials have warned that any recovery would be slow and uneven, and some have predicted the unemployment rate will top 10% before the situation improves.

“Continued household deleveraging and rising unemployment may weigh more on consumption than forecast, and accelerating corporate and commercial property defaults could slow the improvement in financial conditions,” read a report by the International Monetary Fund’s World Economic Outlook, predicting that unemployment will average 10.1% by next year and not go back down to five percent until 2014.

Mark Zandi, chief economist at Moody’s Economy.com, said that “it’s a very fragile and tentative recovery. Policy makers need to do more.”

“The number came in weaker than expected. We saw a lot of artificial involvement by the government to prop up the markets, and now that that is starting to end, the private sector isn’t yet showing signs of life,” said Kevin Caron, a market strategist for Stifel, Nicolaus & Co.

Also on Thursday, the US Commerce Department said factory orders fell for the first time in five months, dropping eight-tenths of a percent in August. Orders for durable goods — items intended to last several years (including everything from appliances to airliners) — fell 2.6%, the largest drop since January of this year.

The US government has been spending billions of dollars — part of a $787 billion stimulus package — to help spark economic growth. There have been some signs the economy is improving.

The Commerce Department said on Thursday that spending on home construction jumped in August for its biggest increase in 16 years. A real estate trade group, the National Association of Realtors, said pending sales of previously owned homes rose more than 12 percent in August, compared to August 2008.

A separate Commerce Department report said that consumer spending, which accounts for more than two-thirds of US economic activity, rose at its fastest pace in nearly eight years, jumping 1.3 percent in August.

Other reports have provided cause for concern. A banking industry trade group said Thursday the number of US consumers making late payments, or failing to make payments, on loans and credit cards is on the rise. A survey by a business group, the Institute for Supply Management, Thursday showed US manufacturing grew in September, but at a slower pace than in August when manufacturing increased for the first time in a year and a half.

Stock markets reacted negatively to the reports. The Dow Jones Industrial Average fell 41 points in early trading, reaching a level of 9467. This follows a drop of 203 points on Thursday, its largest loss in a single day since July. The London FTSE index fell 55 points, or 1.1%, to reach 4993 points by 15.00 local time.

A well-known company offers a variety of modal exciters and performs modal excitation. It is an international company with headquarters based in Cincinnati, Ohio. This company has sales and services locations all around the world such as China, India, Japan, and Korea.

The products manufactured at Xcite Systems Corporation have origins at the University of Cincinnati, Mechanical Engineering Department. This company was founded in 1997 by two former Zonic Corporation executives and provides top quality structural excitation products and services to clients in the automotive, aerospace, shipbuilding, power generation, turbo machinery, and power generation businesses. The very first modal product developed and marketed by Xcite Systems Corporation was the Xcite1300T Systems to meet the needs of the dynamic of automotive drive train and rotating electrical machinery engineers. The Xcite110, Xcite1200, and Xcitre1300 linear exciters were later developed.

Xcite Systems Corporation brought to the market the first commercial linear inertial mass exciter known as the Xcite 1100-5 Inertial Mass System which allowed for testing of structures such as missile silos, cooling towers, bridges, large electric stators, and products where there were no backup fixtures available for modal excitation.

The Xcite 1100 Field Test Series is a portable 1.2 GPM single phase power supply that provides 3000 psi pressure. This product is used by power and natural gas distributors and on ships for structure borne noise path identification.

The Xcite 1100 Laboratory Series is the most popular product. This product is very compact but has a large force capacity and broad frequency range. Due to its compact size, this exciter is often used under vehicles, inside gearboxes, and on drive trains of earthmovers, trains, and large trucks.

The 1100-5 Inertial Mass Modal Excitation system permits testing of structures where backup fixtures are not available or possible. This product is used for the testing of electrical transmission towers, turbine rotors, stators and bearing hoses, generator armatures, windings, diesel engines, motor-generator sets, and on ships for the testing of bulkheads, prop shafts, ands propellers, and structural borne noise isolations systems on submarines.

The Xcite 1200 Series provides medium level force testing for vehicles, trucks, locomotives, off road construction equipment, and power generation equipment such as turbine rotors, generator rotors, stators, and bearings.

The Xcite 1200T-9 Continuous Rotating Torsional Exciter which provides high inertial torque frequencies required for steam turbine rotors, diesel crankshafts, and ship power drive trains.

The Xcite 1300 Laboratory Series allows for frequency responses in the range of 100 to 500 Hz. This product is used for testing of transit vehicles, locomotives, drag lines, backhoes, cranes, truck suspensions and engine mounts, and large energy generating apparatus. This product is also used for testing at nuclear power generation plants.

The Xcite 1300 Torsional Series used for noise tests of structures such as automotive and truck transmissions, prop shafts, axles, differentials, and torsional engine dampers.

In addition to producing various types of these exciters, this company also produces the Reso-NotTM Industrial Damping System (Model Nos. 1206-ZSP-101 AND 1206-ZSP-102) and hydraulic power supplies to work along with exciters.

About the Author: Stewart Wrighter recently met with an engineer who could explain the use of a modal exciter and its benefits. He recently visited a company that developed modal excitation.
