3. SSCD350-1800-4000 Automotive Axle Electric Dynamometer Test Bench System Core Advantages

1) Dual dynamometers work in coordination, providing comprehensive test scenarios: Equipped with dual SSCD350-1800-4000 dynamometers for both drive and load, each unit has a rated power of 350kW, a torque of 1858Nm, and a maximum speed of 4000rpm. It can simulate the dual driving and load conditions of automotive axles in actual operation, covering the full-condition performance testing needs of commercial vehicles and special vehicles axles, and is suitable for torque and speed response verification under different road conditions.

2) Industry-leading measurement accuracy: Utilizing HBM high-precision torque flanges with an accuracy of 0.15%FS, a speed resolution of ±1 rpm, and a dynamic response of ≤1 ms; paired with a Seelong power analyzer with a basic accuracy of ≤0.03%, combined with a multi-dimensional data acquisition system (temperature accuracy ±0.5℃, vibration frequency coverage 10Hz-10kHz), it achieves precise acquisition and analysis of key parameters such as torque, power, temperature, and vibration.
 

3) Strong system stability and compatibility: Siemens variable frequency inverter systems employ vector control technology, featuring triple protection against overcurrent, overvoltage, and overheating, and are compatible with a wide voltage input range of 380V-480V; the battery simulator supports a wide voltage output range of 36-1200V and a high current of ≥1000A, is compatible with 8 types of battery models, and has an energy feedback efficiency of ≥90%, meeting the power matching needs of different vehicle axles while achieving energy saving and consumption reduction.
 

4) Scientific structural design, safe and reliable: The adjustable mounting bracket has a center height of 250-600mm, a load-bearing capacity of ≥1000kg, and a flatness error of ≤0.02mm/m on the mounting surface; the HT350 cast iron plate is combined with a honeycomb shock-absorbing structure to ensure the stability of high-speed testing; the fully enclosed protective cover has built-in sound-absorbing material and is linked to the system (starting and stopping immediately), taking into account both safety protection and noise reduction requirements.
 

5) Intelligent measurement and control, efficient operation: The XLP-1000 measurement and control system is equipped with an I7 industrial computer (32G memory + 1T hard drive), and dedicated software supports working condition setting, real-time data monitoring and automatic report generation; the lubrication station has oil supply pressure regulation, oil temperature control and oil level warning functions, and the dual-circuit design of the chiller is precisely adapted to the cooling needs of the dynamometer and axle, greatly reducing the cost of manual intervention.
