Automotive test solutions, turnkey test stand
EOLexpertise is a leading automotive test solutions manufacturer of end-of-line test benches and components for automotive production lines. Our transmission EOL test benches are turnkey test stand, including automatic transmission test stands, manual transmission test stands, and valve body test stands, for inspecting DCT, CVT, and automated manual transmissions.
Other end-of-line test equipment also includes motor EOL test rig, engine cold test EOL test bench, engine hot test EOL test bed, various dynamometer systems and in-process for engine development (in-process) test bench. Our end-of-line automotive test solutions are optimized for applications that include efficient data acquisition and data management.
The turnkey test stand enables high-resolution and precision pressure, torque and vibration measurements and can be customized to the customer’s requirements.
End-of-line test is a key step in the production process. Production line testing needs to evaluate not only the quality of the product, but also the stability and production volumn. The EOLexpertise transmission, electric motor and internal combustion engine EOL test bench takes the short testing time and can effectively stimulate, measure and verify the functionality of mechanical components.
Transmission EOL turnkey test stands
Transmission EOL test bench test includes NVH test, oil pressure and oil temperature measurement, input and output torque and speed test, clutch test in all speed ranges, shift quality and verification, cooler flow, parking pawl, shift torque and angle and stall test.
Electric motor EOL turnkey test stands
The motor EOL test bench features a soft-start telescopic spline system that protects the customer’s motor product from damage, a product clamping device and a corresponding safety automatic door system that provides a secure interlocking and closing system.
Engine cold test EOL turnkey test stands
In the engine cold test EOL test, the motor is used to rotate the engine crankshaft. The engine is actually not running, so there is no gasoline or special ventilation is required. By comparing the good waveforms of the engine, the common features can be identified to eliminate those engines that are abnormal or faulty.
Automotive test solutions, turnkey test stand for performance
Electrical vehicle powertrain test bench
The automotive test solutions include a load motor, a battery simulator, and an advanced power measurement module (PMM). The battery simulator is an innovative two-way power supply that provides low-power operation through coupled power systems for accurate analog battery and high-speed data acquisition with real-time power measurement modules.
Hybrid vehicle drivetrain test bench
The automotive test solutions for plug-in hybrid vehicle driveline is powered by a proprietary power system using a dual load motor. The inherent modular design approach allows versatility to add optional components such as climatic chamber, power analyser, cooling and heating circuits, and fuel conditioning systems to offer a wide range of possibilities for product validation.
Transmission test bench
The automotive test solutions for transmission is based on three-motor operation logic. An asynchronous motor is used as the input motor drive. Synchronous permanent magnet motors are sometimes considered if the space between the input and output shafts is limited. Two additional asynchronous motors are implemented as wheel outputs.
Engine test bench
In order to reduce engine cost and reliability of output power, engineers should fully consider design factors such as engine indicated power, braking power, fuel consumption, exhaust emissions, engine cooling methods and maintenance. In order to verify the design of the engine, it is necessary to use the engine test rig for engine testing and performance evaluation.
Starter generator test bench
The automotive test solutions for starter generator include a graphical interface, user configurable display and virtual instrumentation. Data collection for all important channels reached 200,000 samples per second. In addition, the tester control is designed for stop-start and change-of-mind (CoM) starters.
