MTS Systems Corporation , incorporated in 1967, is a global supplier of test systems and industrial position sensors located in Eden Prairie, Minnesota, a southwest suburb of Minneapolis. The company provides mechanical test systems, material testing, fatigue testing and tensile testing services, as well as motion simulation systems and calibration services. Examples of MTS products include: hydraulic actuators,rolling road simulators, shaker tables and medical testing equipment.The Company operates in two segments: the Test segment and the Sensors segment. During the fiscal year ended October 1, 2011, the Test and Sensors segments represented approximately 80% and 20% of the company's revenue, respectively. The Test segment provides testing solutions, including hardware, software and after market support. The Sensors segment products are used by industrial machinery and mobile equipment manufacturers to automate the operation of their products.Test SegmentProducts produced by this segment are used by customers in their development of products and certain applications to characterize the products' mechanical properties. MTS' test systems simulate forces and motions that customers' products are expected to encounter in use. A test system includes a load frame to hold the prototype specimen, a hydraulic pump or electro-mechanical power source, piston actuators to create the force or motion, and a computer controller with specialized software to coordinate the actuator movement and record and manipulate results. MTS' Test segment sells a variety of accessories and spare parts, along with services that include installation, calibration, maintenance, training and consulting. The Test segment has a range of customers in the United States of America, Europe and Asia, which respectively represent approximately 30%, 30% and 40% of total orders.Products and customers are grouped into three global markets: Ground Vehicles, Materials and Structures. The Ground Vehicles market consists of automobile, truck, motorcycle, motorsports vehicle, construction equipment, agricultural equipment, rail, and off-road vehicle manufacturers and their suppliers. Test segment system and service products are used in the Ground Vehicles market for the testing of vehicles, subsystems and components. The Materials market covers diverse industries, including power generation, aerospace, vehicles, and bio-medical. Test segment products are sold worldwide through a direct field sales and service organization as well as through independent representatives.The Company’s products and services support customers in the research and development of products through the physical characterization of materials, such as ceramics, composites and steel. Bio-medical applications include systems to test durability and performance of implants, prostheses, and other medical and dental materials and devices. Structures market serves the structural testing needs in the fields of aerospace, wind energy, structural engineering, and petroleum, among others. The aerospace structural testing market consists of manufacturers of commercial, military, and private aircraft and their suppliers. The wind energy market consists of wind turbine manufacturers and their component suppliers. Structural engineering customers include government agencies, universities and the manufacturers of building materials.Sensors SegmentThe industries that use the Company’s Sensor segment’s products include manufacturers of plastic injection molding machines, steel mills, fluid power, oil and gas, medical, wood product processing equipment, mobile equipment, and alternative energy. Sensors segment products are also used to measure fluid displacement, such as liquid levels for customers in the process industries. The Sensors segment manufactures products utilizing magnetostriction technology. MTS has developed an implementation of the technology, known as Temposonics. Its Sensors segment has a range of customers in the United States of America, Europe and Asia represents approximately 25%, 50% and 25% of orders, respectively. Sensors segment products are sold worldwide through a direct sales organization, as well as through independent distributors.MTS Systems Corp. was fined $400,000 after pleading guilty on March 12, 2008 for submitting false US export license applications on proposed shipments to India. The company admitted to two misdemeanor counts of "false certification or writing" by omitting information linked to nuclear power plant test equipment. In March 2011, MTS disclosed that it was again under investigation and barred from bidding on new government contracts. On September 2011 the ban imposed by the Air Force was lifted, allowing MTS Systems to bid on new government contracts and to continue existing government contracts. MTS Systems settled all investigations with the U.S. Government and took measures to ensure government contracting standards were met. "We are happy to put the government investigation behind us. We have made great progress to ensure we meet the U.S. government's contractor standards and we are committed to meeting these requirements every day," MTS Systems CEO Jeffrey Graves said in a statement.

A test system and a method includes applying a test drive signal to a physical test rig having a compliant actuator assembly for imparting loads to a test specimen. An actual response signal of the physical test rig and the test specimen to the test drive signal is obtained and an error as a function of the actual response signal and a selected response signal is calculated. If the error has not reached a selected threshold a new drive signal based on the error and a relaxation gain factor is obtained. The new drive signal is obtained and applied until the error reaches the selected threshold.

An environmental chamber includes an enclosure having opposed walls each wall having an aperture of size to receive a test specimen support therethrough. The apertures are aligned with each other along on a reference axis. A forced air source is configured to supply forced air in a direction to intersect with the reference axis within the enclosure. A diverter is positioned between the forced air source and the reference axis. The diverter is configured to receive the forced air and control the air flow past different portions of the reference axis. The environmental chamber is used with a load frame having test specimen supports extending into the opposed apertures. A method of directing more force air at the test specimen supports than at at least a portion of the test specimen to maintain a selected temperature gradient in the test specimen is also provided.

A force applicator assembly is disclosed to calibrate an in-situ force transducer (or load cell) in a force (load) applying test machine. The force applicator includes stationary member configured to be secured to fixed structure, a moving member, a load cell operably coupled to an end of the moving member, and a differential screw assembly connecting the moving member to the stationary member. A coupling assembly can be used to assure that only tension or compression loads are applied. The coupling assembly can be configured if desired such that no tension or compression loads can be applied. A method to calibrate an in-situ force transducer in a force applying test machine is also provided and uses a force generator and the coupling assembly.

A tire testing machine includes a tire and wheel assembly having a sensor configured to measure a parameter related to the tire and wheel assembly as it rotates on a rotating element. A holder supports the tire and wheel assembly. A processor is configured to receive an input at least based on the output signal from the sensor, and provide an output signal indicative of a parameter of a contact patch between a tire of the tire and wheel assembly and the rotating element. Controlled element(s) are configured to vary a parameter related to the contact patch and/or friction.

In one aspect, a transducer body includes a support having clevis halves. The sensor body includes a generally rigid peripheral member disposed about a spaced-apart central hub joined to each of the clevis halves. At least three flexure components couple the peripheral member to the hub. The flexure components are spaced-apart from each other at generally equal angle intervals about the hub; the sensor body further including a flexure assembly for some flexure components joining the flexure component to at least one of the hub and the peripheral member, the flexure assembly being compliant for forces in a radial direction from the hub to the peripheral member. Each flexure assembly is configured such that forces transferred concentrate strain at a midpoint along the length of each corresponding flexure component.
