AEROSPACE TEST SYSTEMS

AEROSPACE TEST SYSTEMS

  UTM  supports advanced materials testing applications for aerospace with an extensive array of proven solutions. We understand complex materials tests, which often require precise characterization of material behavior under exacting mechanical loads in high-temperature environments, and incorporate multiple methods of correlated data acquisition.   To ensure the safety of designed and manufactured aircraft, mechanical properties are measured and evaluated in terms of their structure, strength, and material performance. Evaluations are performed according to the various environments to which aircraft and space transfer vehicles are directly subjected.   Materials testing for the aerospace industry requires the utmost in experience, responsibility and innovation. There are ongoing advancements in almost every part, component and assembly used in today’s aircraft.   To ensure your product is compliant with RTCA DO-160 and other standards including all related FAA regulations, following types of materials testing  should be done !!!!!    

MECHANICAL TESTING

  Tensile Compression Bearing Shear Flexural Drum peel Crack propagation/crack growth Creep Fatigue ( High-cycle fatigue – Low-cycle fatigue ) Fatigue testing determines both the maximum load a material can endure before failure as well as the total repeated cycles of loading it can withstand before weakening. It helps aerospace manufacturers choose the right materials to survive anticipated stresses without suffering permanent structural changes.  

Impact

  From windshields and nose assemblies to wings and engine housings, impact testing supplies crucial data on a given material’s ability to survive the energy from a measurable impact. Under typically destructive conditions, impact testing yields highly important results for suppliers of parts that are exposed to the elements and the possibility of impact.  

Flammability

  Other than an aircraft’s ability to perform properly, its safety relies heavily on the use of qualified parts and materials that meet all approved safety regulations. One of the most important materials tests related to safety is flammability testing of the textiles, cushions and other manufactured goods found aboard today’s aircraft.  

Thermal

  Often associated with the extreme temperature changes that satellites and spacecraft experience, thermal testing checks to see whether an intended material can survive the drastic thermal fluctuations it will meet once it’s put into service.  

Composition

  Many of today’s aerospace assemblies are made up of composite materials, so it’s important for businesses to know exactly what materials make up these products — frequently resins, thermoplastics and/or carbon fiber assemblies. With composition testing, you know precisely what’s in the materials you’re intending to use.  

Shear

  How much stress must a material survive before rupturing? While the answer to this question is most often found in compliance and regulation standards, the ability to ensure a material — including an adhesive — has the necessary strength for its intended purpose is best achieved through shear testing.  

Thermomechanical analysis

  For materials like glass, polymers, ceramics and laminates, thermomechanical analysis — also referred to as TMA — applies a constant force to determine any linear expansion or phase change a material experiences due to such force.  

Examples of such evaluations include static testing to evaluate the strength and rigidity of aircraft materials and structures, dynamic testing to determine the strength with respect to fatigue and vibrations, and impact testing to evaluate the impact strength and fracture properties.

 

UTM is applying it's technical expertise cultivated through both physical testing in materials development and full-scale testing in quality control in order to develop materials for aerospace applications.

AUTOMOTIVE TEST SYSTEMS
In the production of automobiles, there are many different materials that require mechanical testing. When industry changes occur, this ultimately affects the types of testing being conducted.   Automotive is an extremely competitive industry where material performance will directly affect every part of a consumer’s experience with the vehicle.   Materials testing plays a key role in the automotive industry. Each application within the automotive manufacturing process requires a unique set of testing requirements, be it tensile testing a seat belt, strength testing a clutch, or improving the metal in a car body. And if any product defects do occur along the way, materials testing can beused to determine when and how this happened.   Materials Tests for Automotive Parts Strength of materials is an important component of automotive safety. Because safety is critical, standards are in place to ensure material performance. Thus, when selecting materials, strength must be evaluated to satisfy the standards.   The material strength is largely determined by the composition in metal materials, though with polymers it depends on the type and density of the molecules used. Therefore, a material composition analysis must be done to ensure the material strength is stable. In order to do this, product quality control staff conduct strength evaluations and composition analyses of raw materials used in automobiles, including metals, resins, and other raw materials.   Tensile, compression, bending and hardness tests are used for  strength evaluations. Evaluations of material composition requires inorganic element analysis and compound analysis. Along with acceptance inspections for materials from suppliers, manufacturers also analyze defects during the process and use the information for process improvement. Testing static characteristics of springs, failure tests of parts, and strength evaluations of materials—including metals, plastics, rubbers, and films—is necessary.   These may include acceptance inspections, evaluations of material, and tests to confirm changes in characteristics due to machining.   Testing may be done in accordance with ISO, ASTM, and other standards. Evaluating the car body, engine and suspension is a critical aspect of the testing process. Car doors and hoods are tested to evaluate the strength of the sheet metal used.   Universal testing machines are used to measure the mechanical properties of new lighter weight, high strength alloys used in the production of car body panels and other components.  Both fuel economy and safety are critical to manufacturers, so lightweight, high-strength materials are essential. In order to develop this strong type of sheet metal and perform quality control, tensile testing is must be done. Manufacturers are thus able to determine process-hardening coefficients (n values), rupture strength and elastic modulus.   Tensile Testing is a workhorse of the automotive testing process. In addition to being used for the car body, it is also used to evaluate the O- rings, seat belts and seats. The breaking strength of seat belts is tested—obviously a critical aspect of automotive safety—as well as the foam rubber of a car seat. Car seats are also evaluated using compression testing. As drivers may spend a lot of time in their vehicles, comfort is no small matter. Developing a comfortable car seat takes place through identification of repulsive and restorative forces, then creating a database linked to actualsubjective evaluations. Because of the size of the seats, a wide-design testing instrument is often required.   For manual transmissions, the engine and drive train are connected via the clutch at every change. As you might expect, the clutch functions hundreds or thousands of times during a drive, and requires optimal tuning. For high-output engines, the strength of engine/drive train connection must be sufficient to transmit engine power.   Therefore, strength testing is implemented to evaluate clutch spring force. A machine with a variety of jigs, including compression plates for spring compression, and displacement measuring devices, can enable the measurement of even slight distortions.
RAIL TEST SYSTEMS
Train testing involves putting an entire train – or individual components – through various laboratory and on-track testing under realistic driving conditions to ensure that the rolling stock and railway components are safe in accordance with relevant global standards and regulations. Engineers in the railway sector demand robust and durable measurement hardware systems which, supported by intelligent interaction with software solutions, deliver real-time results and allow the user to easily create reports and analyses. Railway physical tests also include testing under extreme events, like derailment safety tests, rail crash tests or impact tests. Once tests are completed, rolling stock and component manufacturers can learn from the results of the tests and make any necessary improvements. UTM   has been creating tailored products and solutions that meet these high demands of rail vehicle and train testing; from the development phase of a rail vehicle through prototype testing, performance acceptance tests, investigations for improvements and routine monitoring during operation, to tests performed on the tracks and other infrastructure.
