Sany Renewable Energy has put into operation its 35 MW SANY Renewable Energy launches 35 MW drivetrain back-to-back test bench at the company’s Wind Power Testing Centre in China.

The test bench, developed and designed by SANY Renewable Energy, is capable of simulating the full lifecycle of wind turbines up to 35 MW. Equipped with six 100-ton hydraulic cylinders, it applies multi-directional, coordinated loads across six degrees of freedom, allowing for multi-axis stress testing.

With a maximum driving torque of 36 MN•m and a bending moment of up to 80 MN•m, it accurately simulates complex weather conditions and extreme working environments, such as typhoon-level winds.

By utilising high-intensity accelerated fatigue tests, the test bench simulates 20 years of wind farm operation in just one year. It can simultaneously perform functional tests, failure limit verification, and design model validation on the entire turbine and key components such as generators, gearboxes, and main shafts.
