SSCH350-4000/10000 350kW Transmission Type Dynamometer Test Bench System

1) Heavy-duty high-precision measurement: The core torque and speed measurement accuracy reaches the industry-leading level (torque ±0.2% FS, speed ±1r/min), combined with 48 channels of analog signal acquisition and 24 channels of temperature acquisition, comprehensively covering the key performance parameters of heavy-duty transmissions. The data is traceable and exportable, meeting the needs of product certification and scientific research verification.

2) Wide speed and heavy load coverage: 4000-10000rpm rated speed range, rated torque 836Nm, which can be extended to 15000rpm when paired with a heavy load speed increaser. It is suitable for high-speed heavy load testing of heavy-duty transmissions such as ultra-heavy commercial vehicles, construction machinery, and industrial gearboxes, and supports complex working condition simulation such as load simulation and temperature control.

3) Strong adaptability to heavy loads: Designed specifically for high power density transmissions, its heavy-duty mechanical structure, enhanced cooling system, and high-voltage power supply unit are all adapted to continuous heavy-duty conditions and can complete 1000 hours of continuous durability testing.

4) Modular expansion and upgrade: Each system unit is an independent heavy-duty module, supporting power upgrades from 350kW to 400kW, expansion of test channels, and adaptation to new test standards. In the future, it can be flexibly expanded according to production capacity increases or research directions, reducing equipment iteration costs.

5) Stable and reliable under heavy load: The core components are selected from international first-tier brands such as ABB high-power frequency converter and Yokogawa heavy-duty power analyzer. The heavy-duty core dynamometer and measurement and control system are independently developed and have undergone 1,000 hours of heavy-duty operation verification. Equipped with torque calibration device, multiple overload protection and other safety designs, it can operate stably 24 hours a day without worry.

6) Integrated delivery: The entire system of heavy-duty dynamometer, control, data acquisition and protection is pre-integrated. Heavy-duty working condition debugging and calibration are completed in the factory, and the system can be put into use on site, which greatly shortens the project implementation cycle.

7) Heavy-load energy optimization: Adopting the principle of electrical closed testing, the electrical energy generated by the heavy-load dynamometer can be fed back to the power supply system, saving more than 30% of energy costs compared with traditional test benches, and is suitable for continuous heavy-load testing scenarios.
