Understanding Dynamometer Testing
NTS’s dynamometer testing expertise encompasses practically every aspect of a vehicle’s drive train, including transmissions, transaxles, transfer cases, rear axles, U-joints, half-shafts, and complete driveline systems. Innovative on-stand conditioning can induce hot, cold, and special environments on any rotating component. A unique test exposes propshafts to hot, cold, salt/sand slurry, torque, and speed—all while monitoring the bearing temperatures with infrared cameras. Accessory drive components can be exposed to high rpms (up to 9,000 rpm), salt, hot, and cold with simultaneous performance testing.
Understanding EMI/EMC Testing
All contemporary vehicles, including traditional vehicles, are loaded with electronic components. As a result, electromagnetic interference (EMI) and electromagnet compatibility (EMC) are critical for ensuring that a vehicle’s electronic systems and sub-systems perform optimally in a digitally connected world. As the undisputed leader in EMI/EMC testing, NTS provides access to the industry’s top experts for automotive testing—and it boasts the largest collection of EMI/EMC chambers in the Western Hemisphere, which include massive drive-in chambers at different labs. EMI/EMC-related services include electrostatic discharge (ESD), radiated immunity, conducted immunity, and more.
Understanding Electro-Dynamic Vibration
Driving creates constant vibrations on the vehicle’s frame and components. As a result, vibration testing puts the car through extremes to ensure durability. During vibration testing, ambient movements in the building can contaminate the results; but our facility does more, accounting for environmental movement by using high-mass bases and air-bearing pads. These devices ensure our results are accurate. Our testing equipment can exert up to 80,000 with shakers working in tandem, accommodating 60 data channels. Vibration testing helps you improve your component design by identifying weak points when the part gets subjected to random vibrations until failure. Because vibrations occur in all forms of transportation, safety and longevity of parts both rely on being able to withstand constant and erratic movements.
Understanding Environmental and Climatic Simulations
The environment plays a substantial role in the lifespan of automobiles and their components—and we’re able to simulate any environmental condition on earth. As a result, we put parts through environmental simulations to see how long the components last in hot, cold, dry, and wet conditions while also examining UV exposure mixed with salt, fog, dust, and humidity testing. In many areas, such as coastal locations or tropical location, the excessive moisture in the air could cause rusting of the car’s coatings, wearing of the vehicle’s paint or degrading of electrical parts. Because temperature and humidity tend to rise together, we often test both in tandem.
Understanding Mechanical Testing
Mechanical operations can wear over time and become less efficient. With automobiles that rely on both electrical and mechanical systems running at their peak for the vehicle to continue working, physical operation testing is critical. Automotive mechanical tests include examining engine performance and efficiency from a variety of systems. We conduct leak detection, fluid dynamics analysis, stress testing and more. Our testing ensures your engines meet or exceed the regulatory requirements without sacrificing the performance consumers need from your brand.
Understanding Pressure Impulse Testing
Pressure impulse testing puts your system’s hydraulic components through their paces. Multiple systems use fluid movement to create mechanical motion. Regular tests ensure the system maintains pressure and operates as expected for the anticipated lifespan. New designs or models should undergo rigorous testing to prove their performance level matches or exceeds the previous iterations. Pressure impulse testing can help measure the effectiveness of the hydraulic system. At NTS, our pressure impulse testing equipment can test both dynamic and static pressures—and include both rotary and linear servo-hydraulic actuators, reaching beyond 30,000 psi at 30,000 Hz. In addition to examining the impacts of stress during the test, we can also measure torque, strain, flow, and force.
Understanding Emissions Control Systems Testing
Reducing pollution is more important than ever. A single passenger car creates an average of 4.6 metric tons of carbon dioxide annually. In addition to carbon dioxide, internal combustion engines also release other harmful substances. To mitigate the effects of these pollutants on the environment, the federal government has set standards for emissions. Engine components and emissions systems must be tested to determine the amount of greenhouse gases they emit. Without appropriate testing, polluting engines could net their manufacturers hefty fines from both the federal and local governments.
Understanding Emissions Bench Testing
The EPA continues to strengthen requirements for greenhouse gas emissions from on-road vehicles. A typical emissions bench test can measure the amounts of carbon monoxide, methane, hydrocarbons, nitrogen oxides, and carbon dioxide. Adhering to the EPA’s requirements is critical to avoid fines—and requirements are likely to become even stricter over time to reduce greenhouse emissions. Bench testing of gaseous outputs from an engine can verify compliance to guide the manufacturer to make changes to the engine’s design.
Understanding Catalyst Converter Aging
As a catalytic converter ages, it becomes less efficient. The catalytic converter is an essential component of the emission control system. Some states have strict requirements for the catalytic converters that can be installed on cars sold in those places. Catalytic converter function is vital for the engine’s ability to adhere to emissions requirements, and premature failure of a catalytic converter could indicate a product that needs a redesign. These services can test a catalytic converter’s limits without waiting for the average 100,000 miles required to reach its typical lifespan. Additionally, catalytic converters age faster when oil leaks from the engine. The aging test, which is sometimes known as CAT testing, can see what happens to a catalytic converter over time with or without oil contaminating the system.
Understanding SHED Testing
SHED stands for sealed housing evaporative determination. The SHED is a measuring device that measures the emissions from a fuel system or a system component. Unlike other tests that examine individual components, the SHED testing can measure the amount of evaporative emissions from the fuel system. Testing of smaller parts requires mini or micro SHEDs. Measuring the amounts of evaporative emissions means testing the efficiency of the fuel system’s ability to collect and release fuel vapors.
Understanding Canister Load Testing
Canister loading tests the filling and purging of evaporative emissions canisters. Testing the canister load and purge ensures the evaporative emissions system accurately cuts down on pollutants escaping from the fuel system. The ability of a canister to absorb and release fuel vapors is a crucial component of the evaporative emissions system. Without a canister that loads and purges appropriately, the vehicle will be more polluting and run much less efficiently.
Understanding Paint and Coating Tests
Paint and exterior coatings testing services is important for ensuring durability. At NTS, testers subject the paint to multiple stresses. Abrasion testing scuffs the paint to see the level of scratching the paint can withstand. The ability of paint to avoid showing damage from minor scratches is highly desirable for consumers as it increases the lifespan of the vehicle’s coating. Salt fog coating testing replicates the paint’s exposure to road salt or sea salt spray—a service that’s important for places with cold winters or coastal exposure. In addition, we put paint through 1,000 to 2,000 hours of rain and ultraviolet light exposure while simulating from high to low extremes to determine the paint’s strength. Finally, a variety fo chemical resistance tests are available to assess the paint’s response to automotive fluids such as antifreeze, coolant, windshield wiper fluid, oil, and gasoline.
Understanding Gravelometer Testing
Gravelometer testing is another means of measuring a coating’s resistance to abrasions. In a gravelometer test, the samples have 300 pieces of gravel heaved at them by the machine’s air pressure. How much of the coating gets chipped off determines the results of the test. We do our testing to ASTM and SAE standards, ensuring the final scores are trusted and accurate.
